Prevailing dry southwest monsoon conditions across Singapore are driving trader consensus toward a 28°C minimum on September 6, with market-implied odds at 77.5% reflecting official forecasts of nighttime temperatures staying above 27°C amid southeasterly winds and limited cloud cover that reduces radiative cooling. Historical September averages near 25.2°C at Changi have been elevated by persistent haze and suppressed rainfall, while model runs and NEA outlooks emphasize warm, humid nights with minima unlikely to dip to 26°C or below given the current atmospheric setup. Upcoming evening observations from the Meteorological Service Singapore will refine resolution thresholds, though the absence of significant frontal systems or enhanced convection keeps probabilities for cooler outcomes below 6%.

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.
