Recent Met Office guidance and supporting model runs indicate a daytime maximum near 24°C for London on August 28, driven by a transition to southwest winds advecting milder Atlantic air after Thursday’s thundery showers. Partly cloudy conditions with intermittent sunny intervals will permit moderate solar heating, while elevated humidity and scattered showers could cap peaks. Market-implied odds cluster tightly around 23–24°C because small differences in cloud timing or boundary-layer mixing can shift the daily high by 1°C. A 25°C+ outcome remains possible only if stronger insolation develops, but prevailing flow and recent cooling trend make that less probable. Updated forecast guidance expected later today could refine these thresholds.

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.
