Latest National Weather Service and NOAA model guidance indicates a typical midsummer marine air influence moderating Seattle temperatures for July 7, keeping the daily high most likely in the mid-to-upper 70s. Persistent high pressure and reduced cloud cover following early-July variability have supported this range, aligning with climatological norms where July highs average near 78°F and rarely exceed 85°F. Trader consensus reflected in the closely bunched 74–79°F outcomes highlights remaining forecast uncertainty from subtle differences in boundary-layer mixing and onshore flow timing, with new model runs and afternoon observations expected to refine the exact maximum before resolution.
