National Weather Service forecasts for Seattle on August 1, 2026, indicate a high near 72–73°F under mostly cloudy morning conditions transitioning to partial clearing, well below the 79°F daily normal. Persistent onshore marine flow from the Pacific and residual cloud cover are limiting daytime solar heating and keeping temperatures in the lower range, with light variable winds offering little additional warming. Model consensus from recent runs shows minimal deviation, though any earlier clearing or slight offshore shift could push readings into the mid-70s. Trader positioning clusters tightly around the 70–73°F bins, reflecting these stable synoptic conditions and the low likelihood of exceeding typical August variability thresholds.
