Recent National Weather Service guidance and ensemble model runs indicate sunny conditions under a strengthening offshore ridge, favoring maximum solar heating and limited marine air intrusion for Seattle on August 5, which underpins the close trader consensus around 88–91°F. Warmer-than-normal summer outlooks from NOAA and the Climate Prediction Center, combined with a broader Western heat pattern, have lifted expectations above the early-August climatological average high near 79°F, though typical Puget Sound diurnal and topographic variability keeps the 88–89°F and 90–91°F bins nearly tied. Minor differences hinge on exact timing of peak temperatures, subtle shifts in northerly flow strength, or any late-day marine layer development that could cap readings below 90°F versus allowing a brief push into the low 90s.
