Traders assign overwhelming odds to a 33°C high in Kuala Lumpur on September 18 because September climatology and current model guidance converge on that exact value. Equatorial conditions produce typical daily maxima of 32–33°C, with afternoon convection, high humidity near 70–90%, and frequent cloud cover limiting radiative heating. Recent observations from the past week show similar peaks around 33–34°C, and official forecasts for the day consistently project a maximum near 33°C rather than extremes. A realistic shift away from this outcome would require either unusually persistent clear skies allowing greater insolation or a stronger-than-expected rain event suppressing the peak by several degrees.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Kuala Lumpur Intl Airport Station in degrees Celsius on 18 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=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.Traders assign overwhelming odds to a 33°C high in Kuala Lumpur on September 18 because September climatology and current model guidance converge on that exact value.
