Current forecasts from agencies including the Meteorological Service Singapore and international models show September 3 highs near 32°C under partly sunny conditions with typical afternoon convection, aligning with the 33°C outcome's 58.5% implied probability. Singapore's equatorial climate features narrow diurnal ranges around the 31.6°C September mean maximum, where reduced rainfall or lighter winds can push peaks 1–2°C higher, supporting the secondary 34°C share. Recent observations confirm stable trade-wind patterns without anomalous warming, while model consensus on scattered showers introduces uncertainty that caps extreme outcomes below 10% probability. Updated runs ahead of the date will refine these trader-implied odds.

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.
