This market will resolve to the temperature range that contains the highest temperature recorded at the London City Airport Station in degrees Celsius on 30 Mar '26. The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day by the Forecast for the London City Airport Station once information is finalized, 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 to "Yes" until all data for this date has been finalized. 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. Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.Met Office forecasts for Heathrow—the official resolution site for London's highest temperature—project a maximum of 13°C on March 30 amid sunny intervals but persistent cloud cover and westerly winds gusting to 32mph, starting from a chilly morning low near 5°C. Trader consensus on Polymarket tilts toward 12°C at 53% implied probability over 13°C at 34.5%, reflecting uncertainty in afternoon insolation due to partial cloudiness suppressing peak heating, consistent with late March climatology where Heathrow averages 11–13°C highs under Atlantic-influenced westerly flows. Recent overnight model updates held steady at 13°C peaks around 3–5pm, but real-time observations today could shift odds as boundary layer warming interacts with any shower development eastward.
