Dry southwest monsoon conditions and below-average rainfall have kept Singapore's overnight lows elevated on September 9, 2026, with official forecasts from the Meteorological Service Singapore indicating minimum temperatures remaining above 27°C amid warm, humid nights and limited radiative cooling. Current observations and model guidance show diurnal ranges compressed around 27–29°C, consistent with the market-implied odds favoring 28°C (68%) or 27°C (45.5%) as the daily low while assigning minimal probability to 26°C or cooler outcomes. Persistent haze from regional fires and southeasterly winds further suppress temperature drops, aligning with historical September baselines of 25.2°C averages but shifted warmer under prevailing dryness.

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 9 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.Dry southwest monsoon conditions and below-average rainfall have kept Singapore's overnight lows elevated on September 9, 2026, with official forecasts from the Meteorological Service Singapore indicating minimum temperatures remaining above 27°C amid warm, humid nights and limited radiative cooling.
