Trader consensus overwhelmingly backs 5-6 inches of total precipitation at Seattle-Tacoma International Airport (Sea-Tac) gauge for March 2026, driven by the National Weather Service's final climate summary released March 31 confirming 5.42 inches—squarely within that bin based on daily gauge measurements. This above-normal total (versus 3.3-inch climatological average) stemmed from persistent Pacific frontal systems and an early-month atmospheric river delivering steady rain and snowmelt equivalent, per NOAA records. Model forecasts from early March had converged on this range amid neutral ENSO conditions favoring wetter Northwest patterns. With resolution imminent, only a rare post-audit revision by the National Centers for Environmental Information could shift it, though gauge data integrity makes this improbable. Traders await any final NCEI validation expected soon.

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.
