**Trader consensus has converged on a 16°C low for London on August 25, 2026, reflecting real-time observational data from official stations.** Met Office and Heathrow Airport records show overnight minima near 15–16°C under mild, partly cloudy conditions with light easterly winds, consistent with GFS and other model guidance that kept temperatures above seasonal averages (climatological low ~13°C). This outcome aligns with the 15.4°C minimum reported for the day and the absence of any rapid radiational cooling or clear-sky conditions that could drive sharper drops. The near-100% market-implied probability underscores the narrow uncertainty range once the calendar day’s measurements are finalized. Only an unexpected late revision from the primary reporting station or a non-standard measurement protocol would realistically alter the result.

This market will resolve to the temperature range that contains the lowest temperature recorded by NOAA at the London City Airport Station in degrees Celsius on 25 Aug '26.
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
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market can not resolve until the first data point for the following date has been published on the resolution source.
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.**Trader consensus has converged on a 16°C low for London on August 25, 2026, reflecting real-time observational data from official stations.**
