**Trader consensus centers on an 84–85°F high for Seattle on August 4, 2026, reflecting the latest National Weather Service and ensemble model guidance favoring modest warming under building high pressure.** Short-term forecasts show a transition from recent marine-layer influence, which had capped prior days near 74–75°F, to reduced onshore flow and clearer skies that allow greater daytime heating. This aligns with NOAA’s broader seasonal outlook for above-normal temperatures across the Pacific Northwest amid the region’s 14th consecutive warmer-than-average summer. Historical early-August normals near 79°F at Sea-Tac provide context, while climatological data indicate that similar ridge patterns often produce peaks in the low-to-mid 80s before any return of marine air. Key upcoming updates include the next NWS forecast discussion and morning model runs, which could shift probabilities if the marine push strengthens or weakens. The market’s tight clustering around 82–85°F underscores the narrow range of expected outcomes given current atmospheric steering.
