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 has locked in 13°C as the highest temperature in London on April 13 at 100% implied probability, reflecting the official Met Office observation from Heathrow Airport—the standard reference station for such markets—which recorded a maximum of 13°C amid unsettled weather patterns. This aligns with nationwide extremes showing 13.0°C as the UK's highest maximum that day at Altnaharra No. 2, driven by cyclonic systems bringing cooler air, cloud cover, and showers after an early-April hot spell exceeding 26°C in Kew Gardens. April climatology at Heathrow typically sees highs of 12–15°C, supporting this subdued outcome. Realistic challenges would require a rare data revision from measurement error or station-specific microclimate anomaly, though verification processes minimize such risks; the market nears resolution with no further updates expected.
