**Persistent marine layer and onshore flow are anchoring coastal Los Angeles temperatures in the mid-to-upper 70s for August 7, aligning with the market’s leading outcomes of 78-79°F (48.5%) and 76-77°F (34.5%).** National Weather Service forecasts for Los Angeles International Airport (LAX) currently project a high near 77°F under mostly sunny skies after morning patchy fog, consistent with recent model consensus and the 76–78°F range observed in prior days. This pattern reflects typical August coastal dynamics, where the marine layer and westerly winds suppress daytime heating along the immediate coast despite broader seasonal warmth and an evolving El Niño that favors above-average temperatures regionally. Inland valleys may reach the mid-80s or higher, but resolution typically references the cooler coastal station, limiting upside risk. Recent model runs show limited disagreement, with no strong offshore flow or heat dome expected to disrupt the marine influence in the next 24–48 hours. Traders are therefore pricing modest variability around the NWS guidance, with the combined 76–79°F bins capturing over 80% of implied probability. Updated NWS briefings and morning model runs on August 7 will provide the final inputs before resolution.
