Persistent marine layer and moderate onshore flow from the Pacific are keeping trader focus tightly split between 76–77°F and 78–79°F as the most likely highs at the official Los Angeles station on August 6. National Weather Service guidance and ensemble runs show patchy morning low clouds limiting solar heating along the coast while a weak thermal trough tries to develop inland, creating the narrow temperature window. Recent model trends have held steady without major shifts, and historical August coastal climatology supports upper-70s outcomes when the marine influence persists. Updated NWS point forecasts and next model cycles will be the key near-term catalysts that could tip the balance.
