Latest Met Office forecasts and ensemble model runs position a 24–25°C peak as the most probable outcome for London on August 27, reflecting persistent cloud cover, light rain, and a moderating Atlantic airstream that limits solar heating. Early showers and high humidity from overnight thunderstorms give way to a drier afternoon, but residual overcast conditions and southeast breezes cap temperatures below late-summer climatological norms near 27°C. Traders appear to weigh these official guidance updates—showing maxima of 24–26°C with modest warming potential—more heavily than any outlier warmer scenarios, while very low odds on extremes above 27°C or below 23°C align with the narrow uncertainty range in current observational trends and short-range model consensus.

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 27 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.Latest Met Office forecasts and ensemble model runs position a 24–25°C peak as the most probable outcome for London on August 27, reflecting persistent cloud cover, light rain, and a moderating Atlantic airstream that limits solar heating.
