Recent Met Office guidance forecasting a daytime maximum near 21°C for London on August 21, 2026, under high pressure with modest Atlantic flow and variable cloud cover, anchors trader sentiment toward the 21°C and 22°C outcomes. Ensemble runs from the Met Office and ECMWF show afternoon peaks clustered between 20–23°C, with limited potential for stronger warming due to cooling sea breezes and partial cloud. This consensus aligns closely with the market-implied probabilities, where 21°C leads at 40% and 22°C follows at 24%, reflecting calibrated assessment of model spread and historical August variability around the 22°C seasonal average. Updated model runs over the next 48 hours will refine resolution criteria.

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.
