This market will resolve to the temperature range that contains the highest temperature recorded at the London City Airport Station in degrees Celsius on 29 Mar '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.Met Office and BBC Weather's latest forecasts, refreshed on March 28, project London's highest temperature on March 29 at 11°C under light rain showers and moderate north-westerly winds, driving trader consensus to a 57.5% implied probability for that outcome while pricing 10°C at 18% and 12°C at 17.5% to reflect model spread and measurement uncertainty at official stations like Heathrow. Current atmospheric conditions—a weakening frontal system yielding partial cloud cover and breezy conditions—align with late March climatology, where average highs hover around 11°C, limiting intensification potential. Ensemble model guidance shows low risk of extremes beyond 13°C or below 9°C, with final hourly updates expected overnight to refine probabilities ahead of resolution.
