Official National Weather Service observations at Seattle-Tacoma International Airport recorded a daily maximum of 75°F on August 16, 2026, under partly sunny conditions with light northwest winds and no significant marine layer intrusion. This outcome aligned with climatological norms for mid-August, when highs typically average 75–78°F amid weakening onshore flow and modest ridging aloft. Model guidance from the prior week converged on 74–77°F ranges, with limited diurnal heating due to persistent marine influence keeping temperatures below seasonal peaks. Trader consensus reflected this observational certainty once preliminary data posted, though minor discrepancies in station siting or rounding could theoretically shift resolution if post-processed values differ from the primary NWS report.
