High pressure building over the UK, drawing warmer subtropical air northward while promoting clear skies and light winds, forms the main driver behind current Polymarket odds for London's September 21 minimum temperature. Official Met Office guidance and ensemble models indicate overnight lows near 11–14°C under these conditions, with radiative cooling enhanced by reduced cloud cover, though model spreads introduce uncertainty around exact thresholds. Recent nights have recorded minima of 10–13°C amid variable Atlantic influences, supporting trader consensus on outcomes clustered near 8–11°C. Updated forecast runs and surface observations over the next 48 hours will likely refine probabilities ahead of resolution.

The resolution source for this market will be information from NOAA, specifically the lowest 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.
