This market will resolve to the temperature range that contains the highest temperature recorded at the London City Airport Station in degrees Celsius on 13 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 a 14°C high in London on April 13 at 32.5% implied probability, closely trailed by 13°C (24.5%) and 15°C (22.5%), mirroring the Met Office's midday April 11 forecast update projecting a 14°C maximum amid sunny intervals and light showers. This tight clustering stems from ensemble model uncertainty over cloud cover and frontal shower timing during peak afternoon heating (2-4pm), when rain probabilities hit 50%, potentially capping insolation and temperatures below 15°C or allowing brief sunny breaks to push higher. An active jet stream maintains mild Atlantic air masses consistent with April's climatological mean high of ~14°C, though blustery winds add variability. Watch for ECMWF and Met Office revisions this afternoon refining the outlook.
