This market will resolve to the temperature range that contains the highest temperature recorded at the London City Airport Station in degrees Celsius on 15 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.Latest Met Office and BBC Weather forecasts project London's highest temperature on April 15 at 16-17°C under light rain, cloud cover, and moderate southerly breezes, aligning with trader consensus pricing 17°C at 41.5% implied probability, 18°C at 28.5%, and 16°C at 19.5%. This positioning follows last week's record early-April heatwave peaking at 26.6°C in Kew Gardens—driven by persistent high pressure—now displaced by a westerly Atlantic frontal system introducing cooler mid-level air and precipitation, capping daytime heating near seasonal norms of 14-15°C. Short-range model consensus shows limited sunshine potential amid showers, though minor clearing could nudge highs toward 18°C; monitor evening updates from official agencies for final refinements ahead of observational data tomorrow.
