**Trader consensus centers on a 27–28°C daily minimum for Singapore on September 17, 2026, with market-implied probabilities near 58% for those outcomes.** Recent official forecasts from the Meteorological Service Singapore and numerical models indicate overnight lows around 27°C under prevailing southwest monsoon conditions, featuring light southeasterly winds, high humidity above 75%, and variable cloud cover that limits nocturnal radiative cooling. Climatological baselines show September average daily minima near 25.2°C, yet the first half of the month recorded many nights above 27°C amid reduced rainfall and persistent warmth. Current model guidance and local observations point to similar conditions today, with thundery showers possible but unlikely to produce enough evaporative cooling for a notable drop. Differentiation between 26°C and 28°C hinges on exact timing of any clearing skies versus sustained cloud cover and moisture; lower probabilities for 24–25°C or below reflect the low historical frequency of such readings in mid-September without major synoptic shifts. Updated forecasts and real-time observations from Changi or other stations will determine final 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 17 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.**Trader consensus centers on a 27–28°C daily minimum for Singapore on September 17, 2026, with market-implied probabilities near 58% for those outcomes.** Recent official forecasts from the Meteorological Service Singapore and numerical models indicate overnight lows around 27°C under prevailing southwest monsoon conditions, featuring light southeasterly winds, high humidity above 75%, and variable cloud cover that limits nocturnal radiative cooling.
