This market will resolve according to the total precipitation in mm at Heathrow (London Airport) in October, 2026, according to the Met Office.
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 October 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 October 2026 is released.
If the relevant data is not available by January 7, 2027, 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.
