Current forecasts from multiple meteorological models, including those referenced by the National Environment Agency of Singapore and international agencies, indicate nighttime minimum temperatures stabilizing near 26°C on September 12 amid typical southwest monsoon conditions with light southeast winds and high humidity. This aligns with September climatological averages of 25–26°C lows at Changi and other stations, where diurnal ranges rarely dip below 24°C without atypical cooling events. Trader consensus at 93% implied probability for 26°C reflects this model agreement and historical precedent, though heavier-than-expected convective activity or a temporary wind shift could push readings to 25°C or lower before dawn. Updated hourly observations through the night will provide the decisive data for market resolution.

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.Current forecasts from multiple meteorological models, including those referenced by the National Environment Agency of Singapore and international agencies, indicate nighttime minimum temperatures stabilizing near 26°C on September 12 amid typical southwest monsoon conditions with light southeast winds and high humidity.
