**Forecast consensus from the Met Office and other models points to a maximum of 20–21°C in London on September 18, 2026, under partly cloudy skies with southwest winds.** This aligns with typical mid-September climatology for the region, where daily highs average near 19–20°C, and current conditions feature moderate temperatures without strong high-pressure amplification or cold-air advection. Recent model runs show limited day-to-day variability, with the 20°C outcome capturing the bulk of implied probability as the mode of expected maxima. Minor spread in guidance between 19°C and 21°C accounts for the secondary probabilities, reflecting standard ensemble uncertainty in boundary-layer mixing and cloud cover. No major forecast shifts have occurred in the past 24 hours.

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.
