Dry conditions have prevailed across Seattle through mid-October 2026, with only about 0.35 inches of precipitation recorded against a 1991–2020 average of 3.9 inches for the full month. Persistent high-pressure systems have suppressed rainfall, producing mostly sunny skies and negligible accumulations in National Weather Service forecasts for the coming days. The remaining 19 days introduce substantial uncertainty, as Pacific storm tracks or shifts in steering patterns could deliver heavier totals or extend the dry spell. Current model guidance favors below-average rainfall overall, aligning with the market’s highest implied probability on the <1.75-inch bin while leaving room for variability in later October atmospheric dynamics.
