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 4 Sep '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 If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source. In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket. To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C. This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first. 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 forecasts from the Met Office and other models indicate a cloudy Friday with patchy drizzle or light rain moving in from the northwest, limiting solar heating and keeping the daily maximum near 21–23 °C under moderate westerly winds. This setup aligns with early-September climatology for London, where persistent cloud cover typically suppresses peaks by several degrees compared with clearer conditions. Trader consensus reflected in the leading 22 °C, 21 °C, and 23 °C contracts tracks these guidance trends, while lower-probability outcomes above 24 °C would require unexpected clearing or stronger southerly flow not currently indicated by official runs. Updated model guidance and Met Office briefings tomorrow morning remain the key near-term catalysts.
