Trader consensus on Polymarket heavily favors 5-7 inches of precipitation in Seattle for March, with 6-7 inches (37.5%) edging out 5-6 inches (34.0%), reflecting ensemble weather model projections from NOAA and ECMWF showing above-average totals amid a transitioning La Niña pattern that historically boosts Pacific Northwest rainfall. Seattle's March climatological average is about 3.3 inches at Sea-Tac Airport, but recent analogs like March 2023's 5.4 inches and persistent atmospheric river threats differentiate the bins: wetter GFS runs push toward 6-7 inches via stronger onshore flow, while drier CFSv2 outlooks cap at 5-6 inches. Key upcoming NOAA 6-10 day updates and mid-month model refreshes could shift odds, as subseasonal variability remains high.

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.
