**Persistent southwest monsoon conditions and below-average rainfall are keeping Singapore's nights warm, with official forecasts from the Meteorological Service Singapore projecting minimum temperatures above 27°C on most nights through mid-September 2026.** This aligns with prevailing southeasterly winds, fair and occasionally windy weather, and limited cloud cover that reduces nocturnal radiative cooling in the tropical environment. Historical September averages show a mean daily minimum of 25.2°C, but current dry conditions—exacerbated by regional haze potential and possible El Niño influences—support warmer overnight readings around 26–27°C, consistent with short-term model guidance from sources like WeatherBug and GFS data showing lows near 26–27°C (78–81°F) for September 3. Market-implied odds clustered around 25–27°C reflect this consensus, while the elevated probability on 21°C or below highlights residual uncertainty from localized variability or model spread in a region where urban heat islands and humidity typically moderate extremes. New forecast updates from NEA/MSS over the next 24 hours will be key resolution drivers.

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.
