Marine layer and onshore flow from the Pacific are the dominant factors capping temperatures in Los Angeles on August 13, 2026, with National Weather Service forecasts calling for mostly cloudy skies, patchy fog, and highs near 80°F under light southwest winds. This setup favors the market's leading 74–77°F bin as traders incorporate typical summer marine moderation and recent model consensus showing suppressed afternoon heating compared with inland valleys. Historical August averages near 84°F provide context, yet persistent cloud cover and sea-breeze effects have kept recent coastal readings in the mid-70s to low-80s range. Updated NWS briefings and real-time observations at key stations remain the key data releases that could shift implied probabilities before resolution.
