Recent heavy rainfall has already delivered around 50mm to London by mid-June, matching or exceeding typical full-month averages of 50-60mm at sites like Kew Gardens. This early surge, driven by an unsettled atmospheric pattern with multiple low-pressure systems and frontal passages, positions totals near the middle of the distribution. Remaining forecast uncertainty stems from variable jet stream positioning and limited model consensus on late-month stability versus additional showers, with Met Office seasonal guidance indicating a slight tilt toward wetter-than-normal conditions overall. Traders weigh these observed accumulations against climatological baselines and short-range model runs when assessing bins clustered between 50-80mm.

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 June 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 June 2026 is released.
If the relevant data is not available by September 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.
