Recent official forecasts from the Met Office and other models indicate a daytime maximum near 20°C for London on September 17, driven by moderate westerly winds, variable cloud cover, and a chance of morning drizzle that may limit peak heating. This positions 20–21°C as the leading outcomes in trader consensus, consistent with current atmospheric patterns favoring mild rather than unseasonably warm conditions. Afternoon clearing could allow brief spikes toward 21°C, while thicker cloud or earlier precipitation would favor 19–20°C. Historical September averages near 18–19°C provide context, but the near-term forecast updates from monitoring agencies remain the key variable traders are weighting ahead of resolution.

The resolution source for this market will be information from NOAA, specifically the highest 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.
