This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the London City Airport Station in degrees Celsius on 25 Aug '26. The resolution source for this market will be information from NOAA, specifically the highest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=eglc To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C. This market can not resolve until the first data point for the following date has been published on the resolution source. 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. Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.Recent Met Office guidance and ensemble models project a London maximum of 22–25°C on August 25 under mostly cloudy skies with light easterly winds and a modest rain chance. Reduced solar insolation from persistent stratiform cloud, combined with cooler maritime air advection, caps daytime heating below recent warm anomalies. Trader consensus clusters on 22–23°C because these outcomes align with the central tendency of short-range forecasts while accounting for model spread in boundary-layer mixing and cloud timing; higher or lower extremes remain low-probability given stable synoptic patterns through midweek.
