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 heavily favors 15°C (41.5%) and 16°C (36.5%) as the highest temperature in London on April 4, driven by the Met Office's latest short-range forecasts indicating maximums in the mid-teens Celsius amid variable cloud cover and potential brighter spells during the Easter weekend. Recent ECMWF and GFS model runs over the past 24 hours have trended warmer than earlier March 30 outlooks (13°C under persistent cloud), highlighting reduced shower probabilities (20-50%) and gusty winds moderating to light southerlies, enhancing insolation potential to differentiate 15°C from 16°C or 17°C+. Key uncertainty lies in the extent of afternoon cloud breaks, with historical early April baselines around 13°C but analogs showing 2-4°C boosts from high-pressure ridging; watch this morning's Met Office update and Heathrow observations for final guidance.
