This market will resolve to the temperature range that contains the highest temperature reported at Shanghai Pudong International Airport (ZSPD) on 23 Oct '26.

The qualifying value is the highest temperature reported in the hourly temperature remark of any routine (METAR) observation for Shanghai Pudong International Airport (ZSPD) on that date, in tenths of a degree Celsius as reported. A report whose line begins with SPECI is a special observation and does not count. Every other report is routine, including one issued off the nominal hour and one that carries no METAR or SPECI label.

For How to Read the METAR Report, see: https://polymarket-upload.s3.us-east-2.amazonaws.com/market_products/Weather/How+to+Read+the+METAR+Report.pdf

The hourly temperature remark is the group beginning with the letter T followed by exactly eight digits. After the T, one digit for sign (0 positive, 1 negative) and three for tenths of a degree Celsius give the temperature; the following four are the dew point and are not used. T01390133 is 13.9°C; T10171022 is −1.7°C.

If a routine observation does not carry the hourly temperature remark, the temperature group in the body of that observation governs for that observation, in whole degrees Celsius as reported. It appears as temperature and dew point separated by a slash, with M marking a negative value: 18/12 is 18°C; M11/M17 is −11°C. An observation that reports no temperature in either place is disregarded.

Each market in this event states its range in whole degrees Celsius. The qualifying value is rounded to the nearest whole degree, with a value ending in exactly half rounded up to the next higher whole degree, and that whole Celsius value determines which range contains it. For example, 13.9°C counts as 14°C; 17.4°C counts as 17°C; 16.5°C counts as 17°C; −1.7°C counts as −2°C; −8.5°C counts as −8°C.

An observation counts if its time stamp, converted to the station's local time (including any daylight-saving shift in effect), falls on the observation date.

This market will resolve at the issuance of the first METAR observation for the station on the day following the observation date or by 11:59 PM ET on the day following the observation date, whichever comes first. Resolution is determined from the observations the resolution source shows for the observation date.

In the event that the Aviation Weather Center has published no routine observation reporting a temperature for the observation date by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source. In the event that neither source has published data sufficient to determine a temperature for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.

The report the resolution source shows for a given observation time is the one that counts, whether or not it is marked as a correction (COR). Changes to observations within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered. Where the first routine observation for the following date is published before that deadline, resolution is determined from a read taken after it. Where it is not, resolution is determined from a read taken at that deadline.

In the case that the Resolution Source publishes data, sufficient to settle a Market, that is clearly erroneous and the result of technical or operational error, or of unauthorized interference with the Resolution Source or its data, the Market may remain open for a period of up to seven (7) calendar days (ET) from the time of the original release, in anticipation of a correction by the Resolution Source. If the Resolution Source publishes a corrected value within that period, that value will be eligible for resolution. If no corrected value is published within that period, Polymarket will issue a Clarification to determine whether the originally published value may be eligible for resolution, or whether other action is required to preserve the orderly functioning of the Market.

The resolution source for this market will be the routine observations for Shanghai Pudong International Airport (ZSPD) published here:

An observation counts if its time stamp, converted to the station's local time (including any daylight-saving shift in effect), falls on the observation date.

This market will resolve at the issuance of the first METAR observation for the station on the day following the observation date or by 11:59 PM ET on the day following the observation date, whichever comes first. Resolution is determined from the observations the resolution source shows for the observation date.

In the event that the Aviation Weather Center has published no routine observation reporting a temperature for the observation date by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source. In the event that neither source has published data sufficient to determine a temperature for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.

The report the resolution source shows for a given observation time is the one that counts, whether or not it is marked as a correction (COR). Changes to observations within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered. Where the first routine observation for the following date is published before that deadline, resolution is determined from a read taken after it. Where it is not, resolution is determined from a read taken at that deadline.

In the case that the Resolution Source publishes data, sufficient to settle a Market, that is clearly erroneous and the result of technical or operational error, or of unauthorized interference with the Resolution Source or its data, the Market may remain open for a period of up to seven (7) calendar days (ET) from the time of the original release, in anticipation of a correction by the Resolution Source. If the Resolution Source publishes a corrected value within that period, that value will be eligible for resolution. If no corrected value is published within that period, Polymarket will issue a Clarification to determine whether the originally published value may be eligible for resolution, or whether other action is required to preserve the orderly functioning of the Market.

The resolution source for this market will be the routine observations for Incheon Intl Airport (RKSI) published here:

This market will resolve to the temperature range that contains the highest temperature reported at Guangzhou Baiyun International Airport (ZGGG) on 23 Oct '26.

The qualifying value is the highest temperature reported in the hourly temperature remark of any routine (METAR) observation for Guangzhou Baiyun International Airport (ZGGG) on that date, in tenths of a degree Celsius as reported. A report whose line begins with SPECI is a special observation and does not count. Every other report is routine, including one issued off the nominal hour and one that carries no METAR or SPECI label.

For How to Read the METAR Report, see: https://polymarket-upload.s3.us-east-2.amazonaws.com/market_products/Weather/How+to+Read+the+METAR+Report.pdf

The hourly temperature remark is the group beginning with the letter T followed by exactly eight digits. After the T, one digit for sign (0 positive, 1 negative) and three for tenths of a degree Celsius give the temperature; the following four are the dew point and are not used. T01390133 is 13.9°C; T10171022 is −1.7°C.

If a routine observation does not carry the hourly temperature remark, the temperature group in the body of that observation governs for that observation, in whole degrees Celsius as reported. It appears as temperature and dew point separated by a slash, with M marking a negative value: 18/12 is 18°C; M11/M17 is −11°C. An observation that reports no temperature in either place is disregarded.

Each market in this event states its range in whole degrees Celsius. The qualifying value is rounded to the nearest whole degree, with a value ending in exactly half rounded up to the next higher whole degree, and that whole Celsius value determines which range contains it. For example, 13.9°C counts as 14°C; 17.4°C counts as 17°C; 16.5°C counts as 17°C; −1.7°C counts as −2°C; −8.5°C counts as −8°C.

This market will resolve to the temperature range that contains the highest temperature recorded by the Hong Kong Observatory in degrees Celsius on 23 Oct '26.

The resolution source for this market will be information from the Hong Kong Observatory, specifically the "Absolute Daily Max (deg. C)" the specified date once information is finalized in the relevant "Daily Extract", available here: https://www.weather.gov.hk/en/cis/climat.htm

In the event that there is no data for the observation date by 11:59 PM ET on the seventh day following the observation date, this market will resolve to the lowest bracket.

This market will resolve once data for this date has been published on the resolution source, or by 11:59 PM ET on the seventh day following the observation date, whichever comes first.

The resolution source for this market measures temperatures in Celsius to one decimal place (eg, 9.1°C). Thus, this is the level of precision that will be used when resolving the market.

Any revisions published after the Hong Kong Observatory's initial publication of data for this market's timeframe will not be considered for this market's resolution. That initial publication is the revisions cutoff.

In the case that the Resolution Source publishes data, sufficient to settle a Market, that is clearly erroneous and the result of technical or operational error, or of unauthorized interference with the Resolution Source or its data, the Market may remain open for a period of up to seven (7) calendar days (ET) from the time of the original release, in anticipation of a correction by the Resolution Source.

For example, 18.3°C is 64.94°F and counts as 65°F; 17.8°C is 64.04°F and counts as 64°F; 19°C is 66.2°F and counts as 66°F; −22.5°C is exactly −8.5°F and counts as −8°F.

An observation counts if its time stamp, converted to the station's local time (including any daylight-saving shift in effect), falls on the observation date.

This market will resolve at the issuance of the first METAR observation for the station on the day following the observation date or by 11:59 PM ET on the day following the observation date, whichever comes first. Resolution is determined from the observations the resolution source shows for the observation date.

In the event that the Aviation Weather Center has published no routine observation reporting a temperature for the observation date by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source. In the event that neither source has published data sufficient to determine a temperature for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.

The report the resolution source shows for a given observation time is the one that counts, whether or not it is marked as a correction (COR). Changes to observations within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered. Where the first routine observation for the following date is published before that deadline, resolution is determined from a read taken after it. Where it is not, resolution is determined from a read taken at that deadline.

In the case that the Resolution Source publishes data, sufficient to settle a Market, that is clearly erroneous and the result of technical or operational error, or of unauthorized interference with the Resolution Source or its data, the Market may remain open for a period of up to seven (7) calendar days (ET) from the time of the original release, in anticipation of a correction by the Resolution Source. If the Resolution Source publishes a corrected value within that period, that value will be eligible for resolution. If no corrected value is published within that period, Polymarket will issue a Clarification to determine whether the originally published value may be eligible for resolution, or whether other action is required to preserve the orderly functioning of the Market.

The resolution source for this market will be the routine observations for Miami Intl Airport (KMIA) published here:

This market will resolve to the temperature range that contains the highest temperature reported at Kuala Lumpur Intl Airport (WMKK) on 23 Oct '26.

The qualifying value is the highest temperature reported in the hourly temperature remark of any routine (METAR) observation for Kuala Lumpur Intl Airport (WMKK) on that date, in tenths of a degree Celsius as reported. A report whose line begins with SPECI is a special observation and does not count. Every other report is routine, including one issued off the nominal hour and one that carries no METAR or SPECI label.

For How to Read the METAR Report, see: https://polymarket-upload.s3.us-east-2.amazonaws.com/market_products/Weather/How+to+Read+the+METAR+Report.pdf

The hourly temperature remark is the group beginning with the letter T followed by exactly eight digits. After the T, one digit for sign (0 positive, 1 negative) and three for tenths of a degree Celsius give the temperature; the following four are the dew point and are not used. T01390133 is 13.9°C; T10171022 is −1.7°C.

If a routine observation does not carry the hourly temperature remark, the temperature group in the body of that observation governs for that observation, in whole degrees Celsius as reported. It appears as temperature and dew point separated by a slash, with M marking a negative value: 18/12 is 18°C; M11/M17 is −11°C. An observation that reports no temperature in either place is disregarded.

Each market in this event states its range in whole degrees Celsius. The qualifying value is rounded to the nearest whole degree, with a value ending in exactly half rounded up to the next higher whole degree, and that whole Celsius value determines which range contains it. For example, 13.9°C counts as 14°C; 17.4°C counts as 17°C; 16.5°C counts as 17°C; −1.7°C counts as −2°C; −8.5°C counts as −8°C.

An observation counts if its time stamp, converted to the station's local time (including any daylight-saving shift in effect), falls on the observation date.

This market will resolve at the issuance of the first METAR observation for the station on the day following the observation date or by 11:59 PM ET on the day following the observation date, whichever comes first. Resolution is determined from the observations the resolution source shows for the observation date.

In the event that the Aviation Weather Center has published no routine observation reporting a temperature for the observation date by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source. In the event that neither source has published data sufficient to determine a temperature for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.

The report the resolution source shows for a given observation time is the one that counts, whether or not it is marked as a correction (COR). Changes to observations within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered. Where the first routine observation for the following date is published before that deadline, resolution is determined from a read taken after it. Where it is not, resolution is determined from a read taken at that deadline.

In the case that the Resolution Source publishes data, sufficient to settle a Market, that is clearly erroneous and the result of technical or operational error, or of unauthorized interference with the Resolution Source or its data, the Market may remain open for a period of up to seven (7) calendar days (ET) from the time of the original release, in anticipation of a correction by the Resolution Source. If the Resolution Source publishes a corrected value within that period, that value will be eligible for resolution. If no corrected value is published within that period, Polymarket will issue a Clarification to determine whether the originally published value may be eligible for resolution, or whether other action is required to preserve the orderly functioning of the Market.

This market will resolve to the temperature range that contains the lowest temperature recorded by the Hong Kong Observatory in degrees Celsius on 23 Oct '26.

The resolution source for this market will be information from the Hong Kong Observatory, specifically the "Absolute Daily Min (deg. C)" the specified date once information is finalized in the relevant "Daily Extract", available here: https://www.weather.gov.hk/en/cis/climat.htm

In the event that there is no data for the observation date by 11:59 PM ET on the seventh day following the observation date, this market will resolve to the lowest bracket.

This market will resolve once data for this date has been published on the resolution source, or by 11:59 PM ET on the seventh day following the observation date, whichever comes first.

The resolution source for this market measures temperatures in Celsius to one decimal place (eg, 9.1°C). Thus, this is the level of precision that will be used when resolving the market.

Any revisions published after the Hong Kong Observatory's initial publication of data for this market's timeframe will not be considered for this market's resolution. That initial publication is the revisions cutoff.

In the case that the Resolution Source publishes data, sufficient to settle a Market, that is clearly erroneous and the result of technical or operational error, or of unauthorized interference with the Resolution Source or its data, the Market may remain open for a period of up to seven (7) calendar days (ET) from the time of the original release, in anticipation of a correction by the Resolution Source. If the Resolution Source publishes a corrected value within that period, that value will be eligible for resolution. If no corrected value is published within that period, Polymarket will issue a Clarification to determine whether the originally published value may be eligible for resolution, or whether other action is required to preserve the orderly functioning of the Market.

Revisions remain subject to the cutoff above. The only exception is a correction of a clearly erroneous print under the preceding paragraph, which will be used even if published after the cutoff.

For example, 13.9°C counts as 14°C; 17.4°C counts as 17°C; 16.5°C counts as 17°C; −1.7°C counts as −2°C; −8.5°C counts as −8°C.

An observation counts if its time stamp, converted to the station's local time (including any daylight-saving shift in effect), falls on the observation date.

This market will resolve at the issuance of the first METAR observation for the station on the day following the observation date or by 11:59 PM ET on the day following the observation date, whichever comes first. Resolution is determined from the observations the resolution source shows for the observation date.

In the event that the Aviation Weather Center has published no routine observation reporting a temperature for the observation date by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source. In the event that neither source has published data sufficient to determine a temperature for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.

The report the resolution source shows for a given observation time is the one that counts, whether or not it is marked as a correction (COR). Changes to observations within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered. Where the first routine observation for the following date is published before that deadline, resolution is determined from a read taken after it. Where it is not, resolution is determined from a read taken at that deadline.

In the case that the Resolution Source publishes data, sufficient to settle a Market, that is clearly erroneous and the result of technical or operational error, or of unauthorized interference with the Resolution Source or its data, the Market may remain open for a period of up to seven (7) calendar days (ET) from the time of the original release, in anticipation of a correction by the Resolution Source. If the Resolution Source publishes a corrected value within that period, that value will be eligible for resolution. If no corrected value is published within that period, Polymarket will issue a Clarification to determine whether the originally published value may be eligible for resolution, or whether other action is required to preserve the orderly functioning of the Market.

The resolution source for this market will be the routine observations for Adolfo Suárez Madrid-Barajas Airport (LEMD) published here:
