This market will resolve according to the total precipitation in inches in Seattle between April 1 and April 30, 2026, 11:59PM ET according to the National Oceanic and Atmospheric Administration (NOAA). 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.Trader consensus on Polymarket favors 3-3.5 inches of precipitation in Seattle for April at 47.5% implied probability, driven by National Weather Service data showing 1.86 inches accumulated at Seattle-Tacoma International Airport through April 14—0.22 inches above the mid-month normal of 1.64 inches—boosted by a 1.06-inch rainfall event on April 14 following a dry stretch from April 3-9. NOAA's spring outlook signals a 40-50% chance of below-normal precipitation due to high-pressure ridging over the western U.S., tempering expectations for the remaining 16 days against historical April normals of about 2.7 inches. Model ensembles indicate uncertainty in late-month atmospheric patterns, with upcoming NWS daily summaries and forecast updates key to resolution based on official SeaTac totals.
