Persistent marine layer and onshore flow from the Pacific are suppressing daytime warming along the Los Angeles coast, keeping forecast highs at the official KLAX station in the mid-70s for August 15. National Weather Service guidance and recent model runs show continued low stratus, patchy fog, and light sea breezes limiting temperatures to near or slightly below seasonal normals rather than the typical 84–85°F August average. This pattern, reinforced by a weak upper-level trough lingering offshore, has produced consecutive days of 73–78°F readings at the airport, aligning with the market’s heavy weighting toward 74–77°F. Minor warming could occur if the marine layer thins, but current consensus favors the cooler range through the weekend.
