Current forecast models from sources including the Meteorological Service Singapore and international ensembles indicate overnight lows for September 21 near 27–28°C under partly cloudy skies and light southeasterly winds typical of the prevailing southwest monsoon. High humidity near 80–90% and limited radiative cooling from scattered cloud cover are the main factors keeping minimum temperatures from dropping further, while any clearer intervals could allow brief cooling toward 26°C. These conditions align with September climatology for Singapore, where average nighttime lows hover around 25–27°C amid stable equatorial warmth and minimal seasonal variability. Trader consensus favoring 27°C reflects the tight clustering of model outputs, with resolution hinging on the final 24-hour observational data from Changi Airport.

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.
