Persistent southwest monsoon conditions and below-average rainfall across Singapore have sustained dry, fair weather into early September 2026, supporting daily maximum temperatures of 33–35 °C according to the Meteorological Service Singapore. With minimal cloud cover and localized afternoon thundery showers unlikely to develop widely on September 7, surface heating under southeasterly to southwesterly flow favors peak readings near 33 °C, the market’s leading outcome at 68.5 % implied probability. Model guidance and climatological baselines (September mean maximum 31.6 °C) align with this range, while the smaller 20.5 % probability on 34 °C reflects residual potential for brief clear-sky intensification before any late-day convection.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Singapore Changi Airport Station in degrees Celsius on 7 Sep '26.
The resolution source for this market will be information from NOAA, specifically the highest 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.Persistent southwest monsoon conditions and below-average rainfall across Singapore have sustained dry, fair weather into early September 2026, supporting daily maximum temperatures of 33–35 °C according to the Meteorological Service Singapore.
