Forecast models from agencies including Singapore's Meteorological Service indicate overnight lows for September 24 near 25–27 °C under prevailing southwest monsoon flow, with localized thundery showers and extensive cloud cover limiting radiative cooling. Recent observations show minimums consistently above 27 °C in the first half of the month, while scattered convection and high humidity (often exceeding 90% at night) create narrow ranges for the daily minimum. Ensemble guidance shows modest spread in the 24–28 °C band due to timing of showers and wind patterns, explaining the closely matched market probabilities across 24–27 °C outcomes. Updated model runs and official briefings ahead of the 24-hour period will refine these variables before resolution.

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.
