Trader consensus around 40-60 mm for London precipitation in September reflects climatological averages of 50-55 mm driven by seasonal increases in Atlantic low-pressure systems. Key differentiators include the North Atlantic Oscillation phase, which favors wetter outcomes with a positive index and stronger jet stream, versus drier conditions under high-pressure blocking. Sea-surface temperature anomalies in the North Atlantic and evolving ENSO patterns add uncertainty, as do short-term model runs from the Met Office and ECMWF showing variable frontal activity. Historical variability means totals can easily shift across bins with updated September forecasts, keeping probabilities closely matched.

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