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 18 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.
Recent ensemble forecasts from the Met Office and ECMWF place London's overnight minimum for August 18 most likely in the 17–19 °C range, with 18 °C as the central tendency and the primary driver of the closely matched 47 % and 40.5 % market-implied odds for the 18 °C and 19 °C outcomes. Clear to partly cloudy conditions and light winds are expected to allow modest radiative cooling, though the urban heat-island effect in central London buffers extremes. Model spread remains modest after steady consensus over the past 48 hours, reflecting typical uncertainty in boundary-layer processes and any late adjustments in cloud cover ahead of the next forecast cycles.
