Recent official forecasts from Singapore's Meteorological Service indicate a high of 32–34°C for September 21 under prevailing southwest monsoon conditions, with localized afternoon thundery showers likely moderating peak readings. Historical September averages near 31.6°C and recent observations of multiple days above 34°C support the market's strong weighting toward 33°C as the most probable daily maximum. Model consensus points to southeast winds and moderate humidity limiting extreme heat, though brief clear periods could allow brief spikes toward 34°C. Updated National Environment Agency outlooks through late September emphasize this narrow range, aligning trader-implied probabilities with the latest short-term guidance.

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.
