Recent dry conditions through most of August 2026, with only about 3 mm of precipitation recorded by August 24 at London stations, have strongly favored lower monthly totals amid above-average temperatures. Historical August averages range from 52–66 mm, but the current deficit and a shift to unsettled weather with thunderstorms and heavy showers forecast from late August 26 onward—potentially delivering localized 20–30 mm bursts—are unlikely to fully close the gap before month-end. Model consensus and Met Office outlooks point to moderate additional accumulation over the final week, keeping sub-40 mm outcomes as the dominant trader consensus while underscoring forecast uncertainty in convective rainfall totals.

If the reported value falls exactly between two brackets, then this market will resolve to the higher range bracket.
The resolution source for this market will be the Met Office, specifically the figure for August 2026 under "rain mm" at the https://www.metoffice.gov.uk/pub/data/weather/uk/climate/stationdata/heathrowdata.txt link once the Provisional figure for the whole month of August 2026 is released.
If the relevant data is not available by November 7, 2026, 11:59 PM ET, another credible resolution source will be chosen.
The resolution source for this market measures precipitation to 1 decimal place (e.g., 1.5), thus, this is the level of precision that will be used when resolving this market. Any revisions to precipitation recorded after Provisional data is released for this market's timeframe will not be considered for this market's resolution.
