Recent Met Office guidance positions 24°C as the most likely maximum temperature in London on September 7, with regional outlooks allowing for 25°C under lingering warm, humid air before a cooler northwest flow arrives. Model consensus from GFS and ECMWF runs shows afternoon peaks near 23–24°C amid increasing cloud cover and a low shower risk, limiting further warming after today’s 26–27°C readings. This aligns with trader emphasis on the 24°C outcome at 53% implied probability, followed by 25°C at 29.5%. Early September climatology typically sees highs around 20°C, so current conditions reflect a brief warm spell driven by southerly flow that models indicate will moderate overnight. Updated forecasts tomorrow morning will refine the exact peak before resolution.

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.
