Trader consensus on Polymarket strongly favors 5-6 inches of March precipitation in Seattle at 37.6% implied probability, driven by NOAA's Climate Prediction Center outlook signaling above-normal rainfall for the Pacific Northwest amid a developing La Niña pattern that historically amplifies winter-spring storm tracks. Seattle's March climatological normal is about 3.4 inches, per long-term records from the National Weather Service, but dynamical models like ECMWF and GFS ensembles project persistent low-pressure systems funneling moisture from the Pacific, elevating odds for 6-7 inches (18%) and beyond. Recent February's above-average 5.2 inches and early March's wet start reinforce this wet bias, sidelining dry outcomes below 4 inches.

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.
