Recent forecasts from Singapore's Meteorological Service and international models indicate peak temperatures on September 5 likely reaching 32–34°C under prevailing southwest monsoon conditions, with fair to partly cloudy skies and light southeasterly winds limiting cloud cover and allowing strong daytime heating. Official outlooks project daily maxima in the 33–35°C range amid below-average rainfall and elevated regional haze potential, though localized afternoon showers could moderate extremes. Historical September averages near 31°C and current model consensus support the market's heavy weighting toward 33°C as the implied mode, with limited divergence expected before final observational data from Changi or other stations resolve the exact daily high.

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 5 Sep '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.
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.Recent forecasts from Singapore's Meteorological Service and international models indicate peak temperatures on September 5 likely reaching 32–34°C under prevailing southwest monsoon conditions, with fair to partly cloudy skies and light southeasterly winds limiting cloud cover and allowing strong daytime heating.
