Recent forecasts from Singapore's Meteorological Service and NEA point to a maximum of 33°C on September 23, with thundery showers developing in the late morning and early afternoon under prevailing southwest monsoon conditions. These localized storms, driven by daytime heating and humidity levels often exceeding 70%, typically cap afternoon peaks by increasing cloud cover and evaporative cooling. September climatology shows average daily highs near 31.6°C, yet recent days have frequently reached 33–34°C amid drier early-month conditions. The tight market split between 32°C and 33°C reflects uncertainty over exact storm timing and intensity, with official updates from MSS expected to refine the outlook ahead of resolution.

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 23 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.Recent forecasts from Singapore's Meteorological Service and NEA point to a maximum of 33°C on September 23, with thundery showers developing in the late morning and early afternoon under prevailing southwest monsoon conditions.
