**Official forecasts position 21–22°C as the clear consensus range for London's maximum temperature on August 21, 2026.** The UK Met Office predicts a high of exactly 21°C under sunny intervals, with a low of 11°C and only a 30% chance of light rain late in the day. This aligns with broader model guidance showing mild late-summer conditions influenced by Atlantic air masses and moderate westerly flow. Seasonal context reinforces this: August climatological averages in London hover near 22°C, with recent cooling after earlier heat spikes due to changeable pressure patterns and showers. AccuWeather's extended outlook places daily highs between roughly 20.6–23.6°C, while other guidance clusters around 19–22°C depending on exact cloud cover and wind direction. Trader sentiment reflects this narrow scientific window, with 21°C and 22°C capturing 80% of implied probability. Minor upward or downward revisions could occur with the final model runs or local microclimate effects, but the current data strongly favor outcomes near the seasonal norm rather than extremes.

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 London City 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 London City Airport Station, available here: https://www.wunderground.com/history/daily/gb/london/EGLC.
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 position 21–22°C as the clear consensus range for London's maximum temperature on August 21, 2026.** The UK Met Office predicts a high of exactly 21°C under sunny intervals, with a low of 11°C and only a 30% chance of light rain late in the day.
