**Trader sentiment for the highest temperature in Kuala Lumpur on August 21, 2026, centers on 34°C as the dominant outcome (72% implied probability), with 33°C a distant second (19%) and 35°C a slim possibility (8%).** This positioning stems from short-term meteorological guidance indicating afternoon maxima near 33–34°C amid the southwest monsoon regime typical for late August. Scattered cloud cover, moderate humidity, and isolated afternoon thunderstorms promote evaporative cooling and reduced solar heating, preventing sustained peaks at or above 35°C. Official model consensus from regional meteorological sources shows no strong subsidence or clear-sky persistence that would drive an extreme heat anomaly on this date. A strengthening El Niño (Niño-3.4 index exceeding +2.0°C) contributes a broader warm bias across Southeast Asia and is expected to elevate seasonal temperatures, yet current convective patterns and steering flows are capping the daily maximum. Historical August climatology for Kuala Lumpur rarely exceeds 34°C without unusual synoptic conditions, aligning with the market’s heavy weighting toward the 33–34°C band. Updated model runs and observational data closer to peak heating will refine these probabilities, particularly regarding thunderstorm timing and cloud fraction.

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 21 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.**Trader sentiment for the highest temperature in Kuala Lumpur on August 21, 2026, centers on 34°C as the dominant outcome (72% implied probability), with 33°C a distant second (19%) and 35°C a slim possibility (8%).**
