Current forecasts from the Met Office and global models indicate a minimum temperature near 14°C in London on September 12, driven by mild southwesterly flow, high pressure, and limited overnight radiative cooling under partly cloudy skies. This aligns with climatological norms for mid-September, where average lows hover around 12°C, but recent model runs show warmer advection suppressing typical autumn chill. Trader consensus at 95.5% for 14°C reflects this stable pattern and the low probability of sharp drops. A sudden wind shift to northerly flow or clearer skies enhancing heat loss could push readings lower, though ensemble guidance shows limited divergence through the overnight period.

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.
