Official forecasts from the UK Met Office and other models project a maximum temperature of 19–21°C for London on August 29, 2026, driven by persistent rain, heavy showers, and extensive cloud cover under southwesterly flow that limits daytime heating. These conditions, typical of late-summer Atlantic influences, suppress peaks compared to the clearer, warmer 23–25°C readings observed the prior day. Market-implied odds favoring 20–21°C reflect this consensus from real-time observations and ensemble guidance, with lower probabilities on 22°C or 19°C accounting for minor model spread in shower timing and intensity. Updated agency briefings through the morning will further refine resolution criteria based on official maximum readings.

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 29 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 forecasts from the UK Met Office and other models project a maximum temperature of 19–21°C for London on August 29, 2026, driven by persistent rain, heavy showers, and extensive cloud cover under southwesterly flow that limits daytime heating.
