Current forecasts from meteorological agencies point to a peak of exactly 30°C in London today under stable high-pressure conditions and clear skies, driving the market's near-certain consensus at 30°C. Official guidance highlights light winds and strong solar heating as the main factors aligning with this outcome, consistent with typical mid-August patterns where maximum temperatures often reach the upper 20s to low 30s Celsius. Traders' overwhelming positioning reflects aggregated real-money assessment of model consensus rather than any single projection. Uncertainties in localized cloud formation, subtle shifts in the jet stream, or measurement variations at the official London City Airport station could still alter the recorded high.

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 12 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.
