**Traders assign the highest probability (63%) to a peak of 33°C on September 21, followed by 32°C at 25% and 34°C at 10.5%, reflecting consensus around typical late-September conditions under prevailing southwest monsoon flow.** Official forecasts from the Meteorological Service Singapore and NEA indicate afternoon thundery showers, with highs near 33–34°C amid high humidity (60–95%) and light to moderate southeast winds. These convective showers, driven by daytime heating and regional convergence, commonly limit afternoon maxima by enhancing cloud cover and evaporative cooling. Recent observations show early-September peaks reaching 35.3°C at Sembawang, but the second half of the month has trended closer to the 31.6°C climatological average, with most days in the 33–34°C range. Model guidance and historical analogs support 33°C as the most probable outcome before any localized intensification or clearer skies could push readings to 34°C or higher. Official station data from MSS/NEA will determine the exact daily maximum for market resolution.

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.
