Trader consensus has locked in at 100% for 2.5-3 inches of precipitation in Seattle for April 2026, driven by the National Weather Service's official climate summary from Seattle-Tacoma International Airport (Sea-Tac, station CLISEA), confirming a total of 2.77 inches through April 30. This measurement, 0.41 inches below the 1991-2020 normal of 3.18 inches, reflects a drier-than-average month under persistent ridging patterns that suppressed Pacific moisture inflow. Gauge data from automated and quality-controlled observations provide the authoritative evidence, with no rainfall on the final day sealing the total. Realistic challenges are minimal—only a rare post-audit revision by NOAA could shift it, though historical precedents show such adjustments seldom exceed 0.01-0.02 inches. Finalized monthly data expected soon from NOAA will likely affirm resolution.

The resolution source for this market will be NOAA, specifically the figure for April 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 April 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.
