Recent National Weather Service guidance and ensemble model consensus point to a high near 71°F for Seattle on July 26, driven by persistent onshore flow from the Pacific that maintains a cool marine layer and limits daytime heating. Light southwesterly winds, increasing afternoon cloud cover, and possible scattered showers further cap temperatures, consistent with climatological norms for late-July coastal Washington where averages hover around 75°F but marine moderation often suppresses peaks. Trader sentiment clusters on the 70–73°F bins because small shifts in cloud timing or wind direction can swing the daily maximum by 2–3°F, while stronger high-pressure building would favor the lower-probability 74°F+ outcomes. Updated model runs and NWS briefings tomorrow morning represent the key data points that could refine these market-implied odds.
