High pressure over northwest Europe and modest Atlantic flow are positioning 21°C as the leading outcome for London's maximum temperature on August 21, 2026, with the Met Office forecasting a daytime peak of 21°C under partly cloudy skies. Ensemble guidance from the Met Office and ECMWF models shows afternoon highs clustered near this value, with limited potential for modest warming or cooling depending on cloud cover and any lingering showers. This aligns with the market-implied probabilities favoring 21°C (39%) ahead of 22°C (25.5%) and 20°C (21.5%), reflecting trader assessment of forecast consensus and typical late-August variability. Updated model runs and official briefings in the next 24–48 hours will refine resolution thresholds tied to official London observations.

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.
