Trader consensus on Polymarket heavily favors 5-6 inches of precipitation in Seattle for March (37% implied probability), driven by NOAA Climate Prediction Center outlooks signaling above-normal rainfall across the Pacific Northwest amid a transition from El Niño to La Niña conditions, which historically boost wet-season totals. Recent atmospheric rivers in February delivered over 4 inches—well above the 3-inch norm—sustaining the soggy pattern into early March, per National Weather Service observations. Ensemble models from ECMWF and GFS project continued frontal systems, positioning 6-7 inches (25%) as a strong contender, while drier outcomes below 4 inches languish under 1% odds, defying the region's climatological average of 3.1 inches. Upcoming weekly forecasts will refine these market-implied odds.

The resolution source for this market will be NOAA, specifically the figure for March 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 March 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.
