**Current forecasts from Singapore's Meteorological Service and international models indicate overnight lows of 27–28°C on September 6, driven by prevailing southwest monsoon conditions that sustain warm, humid air masses with southeasterly winds and limited nocturnal cooling.** Dry conditions and reduced rainfall have kept minimum temperatures above the September climatological average of ~25°C, with official guidance noting most nights staying at or above 27°C. Recent observations show daytime highs near 32–33°C transitioning to nighttime readings around 27–28°C under partly cloudy skies, consistent with the market's heavy weighting toward 28°C (67%) and 27°C (31.5%). Model consensus and the absence of significant cooling events reinforce these levels, while lower outcomes remain improbable absent unexpected convective activity or measurement revisions.

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.
