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 28 Aug '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 is unavailable or missing for the observation period, Weather Underground will be used as the secondary resolution source. 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 and ensemble model guidance indicate London’s overnight minimum on August 28 will occur in the pre-dawn hours under partly cloudy skies and moderate southwesterly flow, limiting radiative cooling. Forecast lows cluster tightly around 16–17 °C, consistent with late-summer climatology for the region when Atlantic air masses dominate. Current observations show dew points near 14–15 °C and light winds that reduce the chance of sharp drops below this range, while any scattered showers are expected to remain too brief to alter the daily minimum. Market-implied probabilities therefore favor 16 °C as the resolution outcome, reflecting both the narrow forecast spread and the absence of colder northerly intrusions or clear-sky radiative conditions that could push readings lower.
