Traders have converged on 33°C as the near-certain outcome for Kuala Lumpur’s daily maximum on September 15 because official forecasts and real-time observations from multiple models, including GFS and ECMWF runs, consistently project a peak of 33–34°C under typical equatorial September conditions of high humidity, light southeasterly winds, and scattered afternoon convection. Live station data through the afternoon show temperatures cresting near this level without exceeding it, aligning with climatological norms for the Klang Valley where daytime highs rarely deviate sharply absent strong subsidence or clear-sky anomalies. This market-implied certainty reflects aggregated trader assessment of the narrow uncertainty range in short-term numerical weather prediction for the region. A realistic challenge would require an unexpected late-day clearing or localized heat island effect pushing an official reading to 34°C, or measurement timing differences at the primary reporting station shifting it lower.

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 15 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 have converged on 33°C as the near-certain outcome for Kuala Lumpur’s daily maximum on September 15 because official forecasts and real-time observations from multiple models, including GFS and ECMWF runs, consistently project a peak of 33–34°C under typical equatorial September conditions of high humidity, light southeasterly winds, and scattered afternoon convection.
