Official Met Office forecasts for London on August 16 project a daytime maximum near 27°C followed by an overnight minimum of 16°C, with similar guidance from BBC and other models showing 15–17°C lows. This positioning stems from a post-heatwave transition featuring lighter northerly winds, variable cloud cover that limits daytime heating yet allows moderate nocturnal radiative cooling, and a shift toward fresher Atlantic air masses replacing the prior warm, stable high-pressure regime. Ensemble guidance indicates limited model spread around these values, with clear spells overnight supporting the 16–17°C range as the most probable outcome while slight variations in cloud timing or wind could nudge readings one degree either way. Updated short-range model runs and Met Office briefings over the next 48 hours will provide the key data for refining these market-implied odds.

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 16 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.
