National Weather Service forecasts project a daily maximum near 69°F at Los Angeles International Airport on May 17 under persistent onshore flow and a stable marine layer that has kept coastal heating suppressed all week. This setup, reinforced by cooler sea-surface temperatures and limited vertical mixing, aligns with typical May climatology near the coast where afternoon highs often fall several degrees below inland readings. Model consensus shows only modest spread, with slight variations in the timing of any stratus burn-off or wind shifts capable of nudging the peak into the upper 60s or low 70s. Traders are therefore focused on the precise official end-of-day reading at the resolving station, where even small changes in cloud timing or breeze strength can shift the final value across the tightly clustered leading ranges.
