Recent Met Office guidance highlights a minimum temperature near 10°C for London on September 23, driven by high pressure yielding clear skies overnight and a shift to northerly winds that enhance radiative cooling after daytime highs around 22–24°C. Model consensus from multiple sources supports lows in the 10–12°C range, consistent with seasonal September baselines and the absence of significant cloud cover or southerly flow to moderate temperatures. Trader positioning favoring 14–16°C as leading outcomes reflects lingering uncertainty in exact overnight radiative losses and station-specific readings ahead of final verification, with fresh model runs and Met Office updates expected to refine these implied probabilities before resolution.

This market will resolve to the temperature range that contains the lowest temperature recorded by NOAA at the London City Airport Station in degrees Celsius on 23 Sep '26.
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.Recent Met Office guidance highlights a minimum temperature near 10°C for London on September 23, driven by high pressure yielding clear skies overnight and a shift to northerly winds that enhance radiative cooling after daytime highs around 22–24°C.
