Latest Met Office guidance for London on August 19 projects a daytime maximum near 25°C under partly cloudy skies, with overnight minimum temperatures of 15–16°C as a weak front brings increased cloud cover and light winds that limit radiative cooling. These conditions align with broader August climatology, where typical lows range 13–17°C, and recent model runs show limited divergence on the minimum. Trader consensus heavily favors 17°C (54.5% implied probability) and 16°C (23.0%), reflecting the narrow forecast range and modest uncertainty from variable cloud timing. Upcoming evening updates from the Met Office and ECMWF runs could refine the exact low 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 19 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.
Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.Latest Met Office guidance for London on August 19 projects a daytime maximum near 25°C under partly cloudy skies, with overnight minimum temperatures of 15–16°C as a weak front brings increased cloud cover and light winds that limit radiative cooling.
