**Trader consensus strongly favors 27°C as Singapore’s lowest temperature on September 13, 2026, at 97.5% implied probability.** This positioning stems from consistent forecast guidance and real-time observations from the National Environment Agency network, including Changi and other stations, showing overnight minima holding near 27°C amid typical equatorial conditions of high humidity, light southeasterly winds, and partial cloud cover that limits radiative cooling. September climatology supports this range, with average daily minima around 25–26°C but recent nights trending warmer due to prevailing atmospheric stability. Minor model spreads appear in some runs suggesting possible 26°C dips, yet the weight of official guidance and live data keeps 27°C dominant. A realistic challenge would require clearer skies or an unexpected surge of cooler air, though neither is indicated in current National Environment Agency or international model outputs through the resolution window.

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.
