Trader consensus has locked onto a Seattle high of 68–69 °F on October 4, 2026, because official observations at Sea-Tac and Boeing Field recorded a daily maximum in that narrow band after morning fog cleared under a weakening high-pressure ridge. The pattern produced light northerly winds, abundant sunshine by midday, and peak readings near 69 °F by mid-afternoon before onshore flow cooled the region. This outcome aligns with both real-time station data and model guidance that converged on the same narrow range. Only an unverified station discrepancy or post-analysis adjustment to the official record could alter resolution, though such revisions are rare once preliminary climatological data are posted.
