Recent National Weather Service forecasts and multiple model runs indicate a high of 72–75°F for Seattle on August 31 under mostly sunny skies with northerly winds of 10–15 mph, aligning closely with the 74.5°F 1991–2020 climatological average. Stable high pressure offshore and light winds favor efficient daytime heating without excessive warmth, while marine influence and overnight clearing keep overnight lows in the mid-50s. Trader consensus concentrates on the 74–75°F bin as the central tendency, with modest probability on 76–77°F reflecting potential for slightly stronger insolation or model variance in boundary-layer mixing. No major forecast shifts have emerged in the past 24 hours, though final NWS updates on the morning of the 31st will confirm resolution.
