Recent Met Office forecasts for London indicate a Friday maximum near 25°C under a southwesterly flow, with partly cloudy skies and a modest chance of showers that could cap afternoon heating. Ensemble models show modest spread around peak values, reflecting uncertainty in cloud timing and any weak frontal passage that might suppress insolation. This aligns with late-August climatology, where London daytime highs average near 22–23°C but can reach the mid-20s during settled spells. Trader consensus favoring 23–24°C outcomes, with limited probability assigned to 25°C or higher, reflects this balance of guidance against the risk of greater cloud cover or earlier rain. Updated model runs and official briefings over the next 48 hours will likely refine the implied probabilities.

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.
