This market will resolve based on the highest temperature recorded in the 'Daily Observations' table on Weather Underground, not the figure displayed in the 'Day High & Low' summary section; in the event of any discrepancy between the two, the Daily Observations table shall be the primary resolution source not the Day High & Low section. This market will resolve to the temperature range that contains the highest temperature recorded at the Kuala Lumpur Intl Airport Station in degrees Celsius on 23 Aug '26. The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day for the Kuala Lumpur Intl Airport Station, available here: https://www.wunderground.com/history/daily/my/sepang-district/WMKK. To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C. This market can not resolve until the first data point for the following date has been published on the resolution source. 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.
Official forecasts from Malaysia's Meteorological Department project a daily maximum of 34°C in Kuala Lumpur on August 23, aligning with the market's leading 55.5% implied probability for that outcome. In this equatorial climate, August typically features highs averaging 32–33°C under the southwest monsoon, with strong solar insolation, urban heat retention, and light winds occasionally pushing peaks to 34–35°C. Recent conditions show persistent haze and minimal rainfall, which can modestly elevate daytime temperatures by reducing evaporative cooling. Historical data indicate maxima rarely exceed 35°C in August absent strong El Niño influences, which are not expected to peak until 2027. Upcoming model updates from regional agencies will refine these near-term probabilities ahead of the 23rd.
