This market will resolve to the temperature range that contains the highest temperature recorded at the London City Airport Station in degrees Celsius on 4 Apr '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.Trader consensus on Polymarket reflects tight uncertainty in five-day forecasts for London's highest temperature on April 4, with implied probabilities clustered around 14–16°C despite the latest Met Office guidance projecting a cooler high of 12°C under persistent cloud cover and gusty winds up to 34 mph. This divergence stems from model spread between ECMWF and GFS ensembles, where some runs suggest transient high pressure could yield brighter spells and highs nearer climatological early-April averages of 13°C, while others emphasize northerly flows and Atlantic fronts capping warmth via increased cloud and showers. Key differentiators include cloud amount suppressing daytime heating, potential frost risks overnight boosting diurnal range, and steering patterns; watch daily updates from the Met Office through April 2 for refined guidance as resolution nears.
