Trader consensus overwhelmingly favors 2.5-3 inches of precipitation in Seattle for April 2026 (94.8% market-implied probability), anchored by National Weather Service measurements at Seattle-Tacoma International Airport (Sea-Tac, station CLISEA) recording 2.77 inches through April 28 amid mostly typical Pacific Northwest spring patterns. Dry conditions persisted on April 29 with zero measurable rainfall under persistent high-pressure ridging, aligning closely with the 30-year climatological normal of 2.86 inches and recent CoCoRaHS station reports near 2.95 inches. This positioning reflects aggregated observational data from NOAA-affiliated summaries, with minimal intensification risk from current forecast model ensembles showing low precipitation probabilities through April 30. Realistic challenges include an unforeseen late-month atmospheric river surge pushing totals above 3 inches, though steering patterns and ensemble guidance indicate scant likelihood before resolution. Final NWS monthly climate report expected shortly after month's end.

The resolution source for this market will be NOAA, specifically the figure for April 2026 when the "Monthly summarized data" for "Seattle City Area" is selected with the variable set to "Precipitation" at the https://www.weather.gov/wrh/climate?wfo=sew link once that figure is finalized for the whole month of April 2026.
If the reported data falls exactly between two brackets, this market will resolve to the higher bracket.
The resolution source for this market measures precipitation to 2 decimal places (e.g., 1.54), thus, this is the level of precision that will be used when resolving this market. Any revisions to precipitation recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.
