Recent National Weather Service and model guidance indicate moderate onshore flow and a persistent marine layer are the main factors capping Los Angeles daytime highs near or slightly below seasonal norms for July 7, producing the tight clustering of market-implied odds around 72–77 °F. Sea-surface temperatures along the coast remain near or slightly above average, while upper-level ridging associated with the developing El Niño provides only modest warming aloft. Ensemble spreads in short-range models reflect uncertainty in the exact depth and timing of marine-layer clearing, which can shift the daily maximum by several degrees. Latest NWS briefings and 00Z/12Z runs will refine these thresholds ahead of resolution.
