**Dry southwest monsoon conditions, confirmed in the Meteorological Service Singapore advisory issued September 1, are the main driver behind the 66.5% market-implied probability for a 33°C high on September 4.** Prevailing southeasterly to southwesterly winds, below-average rainfall, and mostly fair skies with limited afternoon cloud cover are expected to allow strong daytime heating, consistent with the official outlook of 33–35°C maxima on most days in the first fortnight. Short-range model guidance and hourly forecasts show afternoon peaks near 33°C under these conditions, with only low chances of localized thundery showers that could briefly suppress temperatures. Historical September averages near 31–32°C provide context, but the current dry spell favors the upper end of the normal range. Traders appear to weigh the balance between this consensus forecast and residual uncertainty from possible haze or isolated convection, keeping 32°C as the secondary outcome at 26.5%. Updated official guidance closer to the date will be the key catalyst for any shifts.

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.
