Observed Met Office measurements at Heathrow Airport, the market's resolution source, record just 3-5mm of total precipitation through April 2026—among the lowest on record and only 8% of the 42mm long-term average—driven by persistent high-pressure systems delivering prolonged dry, settled conditions with minimal light rain events early and late in the month. This scientific evidence underpins the 97.8% trader consensus for under 20mm, reflecting real-money bets on finalized data showing negligible accumulation even after recent zero-rainfall days. Only an unforeseen deluge exceeding 15mm on April 30 could challenge this, though current forecast models from the Met Office indicate clear skies and low precipitation risk, with monthly totals due post-resolution.

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