Official forecasts from Malaysia's METMalaysia project a 34°C daily maximum for Kuala Lumpur on September 22 amid scattered afternoon thunderstorms, while several international models cluster nearer 31°C under mostly cloudy skies with 80% rain chances. Persistent humidity above 70%, widespread cloud cover, and the timing of convective storms are the main variables that could suppress peak heating or permit brief clear periods for higher readings. September climatology shows typical highs of 32–33°C, aligning with the closely matched market-implied odds for 31–33°C outcomes. Fresh model runs and official updates over the next 48 hours will clarify steering patterns and storm development.

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=wmkk
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.
