Current forecasts from meteorological agencies indicate a stable high-pressure system over southern England on August 15, 2026, maintaining overnight minimum temperatures at 20°C through limited radiative cooling and mild southwesterly flow. This setup, supported by model consensus on dew points and boundary-layer stability, underpins the market's 100% implied probability for a 20°C low. Historical August climatology for London shows typical minima near 14–16°C, making the current warmth notable. A realistic shift could occur if a cold front arrives earlier than projected or if clearer skies enable stronger nocturnal cooling, though latest guidance shows low likelihood of such changes 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 15 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.
