Trader consensus on Polymarket favors 5-6 inches of March precipitation in Seattle at 38.4% implied probability, driven by persistent atmospheric river patterns and a subtropical jet stream fueling above-normal rainfall across the Pacific Northwest. NOAA records show Seattle's historical March average at 3.3 inches, but February 2024 totals exceeded 6 inches per National Weather Service data, setting a wet precedent. The Climate Prediction Center's outlook tilts toward above-median precipitation through early spring under transitioning La Niña influences, with GFS and ECMWF ensembles projecting multiple heavy rain events. Lower bins like <4 inches languish below 2% amid model consensus for sustained moisture, though storm track uncertainty tempers >8" odds at 13.1%.

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.
