Recent official forecasts from the Met Office indicate a maximum of 27°C for London on September 3, 2026, driven by southwesterly winds and periods of warm sunshine amid partly cloudy conditions, though early observations and some model runs show afternoon peaks closer to 24–26°C. Hourly data reveal temperatures climbing from around 19°C in the morning to mid-20s by afternoon, with humidity near 60% and light precipitation risk limiting further warming. Trader emphasis on 25°C as the leading outcome reflects model consensus around this value and historical September averages near 22°C, while lower probabilities for 27°C or higher account for potential cloud buildup and steering patterns that could cap the daily high. Updated observations later in the day will refine these market-implied probabilities.

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 3 Sep '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 for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source.
In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
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.Recent official forecasts from the Met Office indicate a maximum of 27°C for London on September 3, 2026, driven by southwesterly winds and periods of warm sunshine amid partly cloudy conditions, though early observations and some model runs show afternoon peaks closer to 24–26°C.
