Marine layer influence and coastal cooling patterns position 78-79°F as the leading outcome for Los Angeles' official high on July 28, with National Weather Service guidance indicating a Tuesday maximum near 79°F at LAX amid persistent onshore flow and morning cloud cover. Recent model runs show minimal warming potential compared to inland valleys, where highs have recently exceeded 100°F during the broader heat episode. Trader consensus around the 78-81°F bins reflects these verified forecast trends and historical July coastal averages near 75-82°F, while lower-probability bins above 84°F account for any rapid marine layer dissipation before peak heating. Updated NWS briefings and observational data ahead of Tuesday will refine resolution around the 2 p.m. observation window.
