Resolution rules

This market will resolve according to the total precipitation in mm at Heathrow (London Airport) in November, 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 November 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 November 2026 is released. If the relevant data is not available by February 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. In the case that the Resolution Source publishes data, sufficient to settle a Market, that is clearly erroneous and the result of technical or operational error, or of unauthorized interference with the Resolution Source or its data, the Market may remain open for a period of up to seven (7) calendar days (ET) from the time of the original release, in anticipation of a correction by the Resolution Source. If the Resolution Source publishes a corrected value within that period, that value will be eligible for resolution. If no corrected value is published within that period, Polymarket will issue a Clarification to determine whether the originally published value may be eligible for resolution, or whether other action is required to preserve the orderly functioning of the Market.
