London's September precipitation typically averages 50-70 mm according to Met Office 1991-2020 normals for the region, driven by the increasing frequency of Atlantic frontal systems as the jet stream strengthens and shifts southward in early autumn. With the month just beginning on September 1, 2026, trader consensus centers on the 50-60 mm bin because historical variability—ranging from under 30 mm in settled years to over 100 mm during persistent low-pressure sequences—creates substantial uncertainty around exact totals. Key differentiating factors include the position and persistence of the polar jet, sea surface temperatures influencing storm intensification, and the balance between westerly moisture advection versus transient high-pressure ridges; updated model runs over coming weeks will clarify whether early-month Atlantic depressions push accumulations higher or allow drier conditions to dominate.

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.
