**Trader consensus on a 13°C low for London on September 5, 2026, stems from consistent official forecasts and model guidance showing clear or partly cloudy skies, light westerly winds, and radiative cooling overnight under high pressure.** Met Office and GFS-based outlooks project daytime highs near 21–23°C followed by a minimum of 13–15°C (roughly 55–59°F), aligning with typical early-September climatology for the region. This setup favors the precise threshold captured by the 99.5% implied probability. Realistic challenges include unexpected increases in cloud cover or stronger winds that limit cooling, or a shift in air mass that raises the overnight minimum above 14°C. Updated model runs and Met Office briefings remain the key near-term data points that could adjust positioning.

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.
