Persistent rain and thick cloud cover from an Atlantic front are suppressing daytime solar heating across London on September 8, keeping maximum temperatures near or slightly below the early-September average of 19–20 °C. Official guidance from the Met Office and ensemble model runs show persistent precipitation through the morning, followed by gradual clearing under strengthening westerly winds that advect cooler maritime air. This setup favors a peak near 19 °C, with 20 °C possible only if breaks in cloud allow brief insolation; lower outcomes hinge on heavier or more prolonged rain. Market-implied odds reflect this narrow scientific uncertainty, with traders weighting the latest model consensus and historical analogs for similar synoptic patterns. Updated NWP runs and Met Office briefings ahead of resolution will be the next key inputs.

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 8 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.Persistent rain and thick cloud cover from an Atlantic front are suppressing daytime solar heating across London on September 8, keeping maximum temperatures near or slightly below the early-September average of 19–20 °C.
