Recent forecasts from official monitoring indicate overnight lows near 27–28°C for Singapore on September 17 under prevailing southwest monsoon conditions, with persistent cloud cover and high humidity limiting nocturnal radiative cooling. This aligns with the first-half September pattern of minimum temperatures remaining above 27°C on many nights, consistent with National Environment Agency observations. Market-implied odds favoring 28°C reflect these conditions and climatological baselines for the month, where typical minima hover around 25°C but recent warmth has shifted the distribution higher. Traders appear to discount cooler outliers absent a significant change in steering patterns or rainfall that could enhance cooling. Updated model runs and evening observations will provide the next key data points for 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.Recent forecasts from official monitoring indicate overnight lows near 27–28°C for Singapore on September 17 under prevailing southwest monsoon conditions, with persistent cloud cover and high humidity limiting nocturnal radiative cooling.
