Recent short-range forecasts from regional models indicate Singapore's minimum temperature on September 12 will most likely fall between 26–27°C under prevailing southwest monsoon conditions, with scattered showers and southeasterly winds limiting nocturnal radiative cooling. Persistent regional haze from Sumatran fires and elevated humidity near 75–85% further stabilize overnight lows near climatological norms, while any clearer intervals could allow modest drops toward 25°C. Trader sentiment remains split between the 22°C-or-below and 32°C-or-higher brackets because model runs continue to diverge on cloud cover and rainfall timing, both of which directly influence the daily minimum recorded at official stations such as Changi. With resolution imminent, the next 48-hour observational updates from Singapore’s Meteorological Service will determine whether the minimum aligns with the narrower 25–28°C cluster or deviates under unexpected convective activity.

This market will resolve to the temperature range that contains the lowest temperature recorded by NOAA at the Singapore Changi Airport Station in degrees Celsius on 12 Sep '26.
The resolution source for this market will be information from NOAA, specifically the lowest 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.Recent short-range forecasts from regional models indicate Singapore's minimum temperature on September 12 will most likely fall between 26–27°C under prevailing southwest monsoon conditions, with scattered showers and southeasterly winds limiting nocturnal radiative cooling.
