Trader consensus on Polymarket heavily favors 5-6 inches of precipitation in Seattle for March (88% implied probability), driven by NOAA's Climate Prediction Center outlook signaling above-normal rainfall probabilities across the Pacific Northwest amid developing La Niña conditions. La Niña, characterized by cooler equatorial Pacific sea surface temperatures, historically boosts winter and early spring precipitation in the region by strengthening the storm track, with Seattle's March average of 3.3 inches often exceeded by 50% or more in such phases. Recent observational data from October-November 2024 confirms the transition from neutral ENSO toward La Niña by December, aligning long-range models like CFSv2 with totals in the 5-6" band. Upcoming monthly outlooks in early March could refine these market-implied odds as real-time data emerges, though seasonal forecasts carry inherent uncertainty from atmospheric variability.

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.
