Southwest Monsoon conditions and below-average rainfall through late August have kept Singapore’s daily maximum temperatures elevated, with many days exceeding 33°C and peaks reaching 34.9°C earlier in the month. Official Meteorological Service Singapore guidance for the period forecasts typical maxima of 33–34°C, occasionally touching 35°C, consistent with the market’s strong weighting toward 33°C (53%) and 32°C (36.5%). Model runs and shorter-range forecasts show partly cloudy skies with afternoon thunderstorm chances on August 31 that could cap heating near 31–32°C depending on cloud cover and timing. Historical August averages near 31.4°C provide context, but the current drier pattern supports the modest upward shift in trader-implied probabilities ahead of final observational data from Changi and other stations.

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 31 Aug '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.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market can not resolve until the first data point for the following date has been published on the resolution source.
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.
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.Southwest Monsoon conditions and below-average rainfall through late August have kept Singapore’s daily maximum temperatures elevated, with many days exceeding 33°C and peaks reaching 34.9°C earlier in the month.
