The official forecast from Malaysia’s Meteorological Department (METMalaysia) projecting a daytime maximum of 34°C under southwest monsoon flow and partly cloudy skies with limited afternoon convection has anchored trader consensus at this level for Kuala Lumpur on August 19. This aligns closely with the long-term August climatology of 31–33°C highs, where high humidity (70–85%) and equatorial insolation typically produce peak readings near this threshold before any evaporative cooling from scattered showers. Model consensus from sources including the Met Office and AccuWeather supports similar values, reinforcing the market-implied odds. Realistically, stronger or earlier thunderstorm development than anticipated could enhance cloud cover and lower the actual high by 1–2°C, while measurement discrepancies at the official station remain a low-probability resolution risk.

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 19 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.
