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 28 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 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.
Official Met Office forecasts for London on August 28 project a daytime maximum of 24°C amid mostly cloudy conditions and moderate southwesterly winds, aligning closely with the market's leading 24°C (45%) and 23°C (28.5%) outcomes. Late-summer climatology favors highs near 22–23°C, with current guidance reflecting mild Atlantic airflow and limited solar heating due to cloud cover that may cap peaks. Model consensus shows low precipitation risk and stable steering patterns, though minor variations in cloud timing or wind strength could shift the observed high by 1°C. Updated Met Office briefings and hourly model runs remain key near-term catalysts for any probability adjustments.
