Trader consensus on Polymarket clusters around 56-63°F for Seattle's April 4 high temperature, with 58-59°F leading at 26.5% implied probability, reflecting National Weather Service guidance and GFS/ECMWF ensemble means near 57°F amid a NOAA spring outlook for warmer-than-average, dry conditions in western Washington as La Niña transitions to ENSO-neutral. This tight spread stems from day-6 forecast uncertainty, where +/-3-5°F model divergences hinge on the timing of a weak upper trough exit versus building ridging aloft, onshore flow strength delivering persistent marine stratus over Puget Sound, and potential afternoon boundary-layer mixing enabling sunbreaks. Historical April 4 highs average 56°F; watch daily NWS updates and fresh model runs for shifts ahead of resolution.
