Singapore's equatorial climate produces stable daily highs typically ranging 31–33°C in September, with the long-term average maximum near 31.6°C at Changi. Current southwest monsoon conditions and persistent dry weather have supported slightly elevated readings, with official guidance indicating maxima of 33–35°C on most days into early September. Short-range forecasts for September 6 converge on afternoon peaks of 32–34°C under partly cloudy skies and moderate southeast winds, limiting rapid intensification or cooling. These factors underpin the dominant 33°C outcome in trader positioning, while the modest probabilities for 34°C or higher reflect the narrow historical window for outliers above 34°C and the moderating influence of humidity and scattered cloud. Updated model runs and any late-day observations will refine resolution near the 35°C threshold.

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.
