Forecasts from Singapore's Meteorological Service and international models point to a daily maximum near 31–32°C on September 11, aligning with the September climatological average of 31.6°C at Changi. Persistent southeasterly flow and afternoon thundery showers typical of the late Southwest Monsoon period are expected to limit peak heating, while transboundary smoke haze from Sumatran and Kalimantan fires has reduced insolation in recent days, exerting a modest cooling influence. Official observations show recent maxima in the 30–32°C range with no significant warm anomalies, keeping 31°C and 32°C as the dominant market-implied outcomes ahead of the daily resolution from the national climate station.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Singapore Changi Airport Station in degrees Celsius on 11 Sep '26.
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.Forecasts from Singapore's Meteorological Service and international models point to a daily maximum near 31–32°C on September 11, aligning with the September climatological average of 31.6°C at Changi.
