Recent National Weather Service forecasts for Seattle on July 18 indicate a high near 76°F under mostly sunny skies with light northwest winds, aligning with the tight clustering of market-implied odds around 74–77°F. Model consensus from NOAA and others supports this range amid typical mid-July marine influences from Puget Sound, which can moderate peaks through onshore flow or afternoon sea breezes. Subtle differences in cloud cover timing, exact wind shifts, or boundary-layer mixing could shift the daily maximum by a degree or two, creating the observed near-even split between adjacent bins. Historical July averages near 76°F provide context, while the close probabilities reflect genuine forecast uncertainty resolvable only by official observations.
