**Strong high-pressure conditions and residual heat from prior days have kept London's overnight minimum at 22°C, aligning with Met Office observations and real-time data.** A dominant anticyclone has limited radiative cooling after daytime peaks reached 33–37°C on August 13, maintaining elevated surface temperatures through the night. This setup produces the market's near-certain 22°C outcome, as traders incorporate official measurements showing minimal temperature drop. Forecast models and station data confirm the lack of significant cooling factors like clear skies with light winds under stable high pressure. Historical August baselines in London typically allow lows near 14–17°C, but the current heatwave anomaly sustains higher minima. Realistic challenges remain limited: a sudden increase in cloud cover, stronger winds, or localized measurement discrepancies at the recording station could theoretically shift the exact minimum by 1°C, though current conditions make this improbable before resolution.

This market will resolve based on the lowest 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 lowest temperature recorded at the London City Airport Station in degrees Celsius on 14 Aug '26.
The resolution source for this market will be information from Wunderground, specifically the lowest 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.
