Forecast models from regional meteorological sources indicate Kuala Lumpur's overnight minimum on September 11 will likely settle near 23–26°C amid persistent monsoon trough influences and scattered thunderstorms. High humidity and extensive cloud cover limit radiative cooling after sunset, supporting the elevated market-implied odds for a 31°C-or-higher minimum, while any brief clearing could allow greater heat loss and push readings toward the 21°C-or-below outcome. Steep vertical temperature gradients typical of the equatorial wet season, combined with light variable winds, create narrow resolution windows around the 24–27°C levels where probabilities cluster tightly. Updated guidance on convective timing and local urban heat-island effects will refine these ranges ahead of the daily minimum observation.

The resolution source for this market will be information from NOAA, specifically the lowest 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.
