Recent cooling following the intense mid-August heatwave—peaking near 34–38°C around August 13—has shifted trader focus toward more typical late-summer conditions for London on the 16th. Official guidance from the Met Office and BBC Weather indicates sunny intervals with light northerly winds and daytime maxima of 24–27°C, aligning with the tightly bunched market probabilities around those thresholds. Key differentiating factors include small variations in forecast cloud cover, the precise timing of any weak Atlantic front, and ensemble spread in maximum temperatures, all of which can shift the daily peak by 1–2°C. Historical August averages near 22°C provide context, but the current setup shows only modest above-normal potential without renewed high pressure or strong insolation. Updated model runs and official briefings over the next 48 hours will likely refine these odds.

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 16 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.
