Recent Met Office and ensemble model guidance indicate overnight lows in London on September 3 will likely settle near 18–19 °C under a mild southwesterly flow and extensive cloud cover that limits nocturnal radiative cooling. These conditions follow a pattern of above-average temperatures persisting into early September, with forecast minimums several degrees warmer than the 1991–2020 climatological low of roughly 12–13 °C. Trader emphasis on the 18 °C and 19 °C contracts reflects the narrow spread across updated model runs and the absence of any incoming cooler air mass before resolution. Light showers or drizzle expected during the day are unlikely to alter the overnight minimum, while any clearing skies could allow modest further cooling toward 17 °C. Updated Met Office and ECMWF guidance issued in the next 24–48 hours will provide the key data points for final positioning.

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 3 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 and ensemble model guidance indicate overnight lows in London on September 3 will likely settle near 18–19 °C under a mild southwesterly flow and extensive cloud cover that limits nocturnal radiative cooling.
