Current forecasts from agencies including the Met Office indicate overnight lows near 15°C across London on September 6 under mild, partly cloudy conditions with light southerly winds and limited radiative cooling. This aligns with model consensus showing minimum temperatures holding at or above that threshold, consistent with above-average September readings relative to the 1991–2020 climatological low of roughly 12°C. Trader consensus at 99.5% for a 15°C floor reflects these verified projections and the narrow window for resolution. A realistic shift could occur if clearer skies overnight enhance cooling beyond model guidance or if localized observations record a dip to 14°C before dawn.

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.
