London's August 2026 precipitation totaled just 12 mm according to station data, far below the 52 mm long-term average and well under the 30 mm threshold. Persistent high-pressure systems, above-average temperatures reaching 37.7 °C, and minimal frontal activity produced widespread dry conditions across southeastern England, where regional totals reached only 35.2 mm or 56 % of normal. Official Met Office summaries confirm eight of nine UK regions recorded below-average rainfall, with drought declarations persisting through late August. Traders' 97.5 % implied probability on the <30 mm outcome directly tracks these verified measurements. Only substantial late-month revisions to official totals or reclassification of trace events could alter resolution.

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.
