Official forecasts from the UK Met Office indicate London highs near 21°C on August 21, 2026, amid a post-heatwave cooling trend after earlier August peaks exceeding 38°C elsewhere in the UK. Ensemble model runs show limited variability, with Atlantic fronts bringing cloud and light rain that suppress maximum temperatures below seasonal averages of 22°C. Historical analogs from similar late-summer patterns confirm subdued readings when high pressure weakens, while Met Office updates and any revised ECMWF guidance represent the next key data points likely to shape trader assessments of temperature thresholds.

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.
