Trader consensus overwhelmingly favors 31°C as Singapore’s highest temperature on October 15, reflecting stable tropical conditions and National Environment Agency forecasts showing a maximum near that threshold. October falls in the inter-monsoon period, when typical daily highs range 30–32°C under moderate humidity and light winds, with minimal deviation from climatological baselines. Official observations from Changi and other stations confirm no heatwave drivers such as strong subsidence or anomalous sea-surface temperatures are present. While rare convective bursts or localized urban heating could push readings slightly higher, historical data and model consensus indicate these scenarios remain low-probability on this date. Final station measurements will determine resolution.
Rules
This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Singapore Changi Airport Station in degrees Celsius on 15 Oct '26. The resolution source for this market will be information from NOAA, specifically the highest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=wsss If NOAA data for the observation date is unavailable 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 there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket. To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C. This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first. The resolution source for this market measures temperatures to whole degrees Celsius (eg, 9°C). Thus, this is the level of precision that will be used when resolving the market. 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 to temperatures recorded 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.
