**Trader consensus on 33°C as the highest temperature in Singapore on September 21, 2026, reflects the Meteorological Service Singapore’s fortnightly outlook projecting daily maxima of 33–34°C on most days, with potential for 35°C only sporadically.** Current model runs and real-time observations show afternoon thundery showers developing under prevailing southeast monsoon flow, which increases cloud cover and limits solar heating during peak insolation hours. These localized convective systems, typical for late September, cap surface temperatures near the lower end of the seasonal range. The 95.5% market-implied probability aligns with this consensus while acknowledging residual uncertainty from variable shower timing; a brief delay in convection or reduced humidity could allow readings to reach 34°C, though sustained clear conditions required for higher values remain unlikely given ongoing regional moisture. Resolution will hinge on the official MSS maximum recorded at designated stations.

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.
