Recent official forecasts and model runs for Kuala Lumpur on September 18 indicate a hazy, humid environment with light variable winds and afternoon convective activity, producing highs most likely between 31–33 °C. Regional biomass-burning haze from Sumatra has reduced incoming solar radiation in recent days, while high moisture content and the intertropical convergence zone favor scattered thunderstorms that can cap daytime peaks through cloud cover and evaporative cooling. These competing influences—haze dimming versus potential breaks in cloud allowing brief warming—create the narrow spread in market-implied probabilities across 31–33 °C outcomes. Updated METMalaysia guidance and short-range model consensus expected in the next 24–48 hours will further refine the most probable maximum.

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.
