This market will resolve to the temperature range that contains the lowest temperature recorded by NOAA at the London City Airport Station in degrees Celsius on 6 Sep '26. The resolution source for this market will be information from NOAA, specifically the lowest 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.
Current forecasts from the UK Met Office indicate a minimum temperature of around 15°C overnight into September 6, 2026, with early morning readings stabilizing near that level under partly cloudy skies, light southerly winds, and moderate humidity before daytime highs reach 26°C. This aligns with recent model runs showing limited radiative cooling due to cloud cover and the mild air mass in place, consistent with the strong market-implied odds favoring 15°C as the daily low. Historical September averages near 12°C provide context, yet current observational trends and ensemble guidance support the consensus. A realistic shift toward 14°C or lower would require clearer skies overnight or a sharper drop in dew points than projected, while any upward revision in models could still resolve at the dominant threshold.
