Singapore’s equatorial climate under prevailing Southwest Monsoon conditions typically produces daily maximum temperatures of 31–33 °C in early September, with Changi normals at 31.6 °C. Current official guidance and numerical model consensus for 10 September 2026 indicate a peak near 32 °C amid partly cloudy skies, scattered afternoon thunderstorms, and light southeasterly winds that limit extreme heating or cooling. High humidity and modest insolation keep the diurnal range narrow, supporting the market’s near-certain 32 °C outcome. Only a sharp, unexpected increase in convective rainfall or an unforecast clearing that boosts insolation could realistically push the high outside the narrow 31–33 °C band before the observation window closes.

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.
