Recent Met Office seasonal outlooks signal below-average precipitation for London in March, driven by persistent high-pressure dominance over southern England and a negative North Atlantic Oscillation phase limiting Atlantic moisture influx, positioning the 20-30mm bin at 56.3% market-implied probability as trader consensus. Ensemble forecasts from UKMO and ECMWF models show rainfall totals clustering 15-35mm, consistent with January-February's drier-than-normal trends (London Heathrow ~20% below 1991-2020 averages) and historical dry March analogs under similar blocking patterns. Uncertainty persists from potential jet stream shifts; the next three-week outlook, expected mid-February, could adjust guidance amid inherent model spread for spring transitions.

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 March 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 March 2026 is released.
If the relevant data is not available by May 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. If relevant data is not released by May 7, another resolution source will be chosen.
