Recent National Weather Service forecasts for downtown Los Angeles point to a May 22 high near 68–69°F, driven by a persistent marine layer off the Pacific that moderates daytime warming and limits solar heating. This places the 68–69°F bin at the top of trader sentiment, though closely matched probabilities for 66–67°F and 70–71°F reflect lingering model spread on exact cloud timing and sea-breeze onset. Historical May averages for the region hover in the mid-70s, so current cooler readings stem from stronger onshore flow and lower 500-millibar heights than typical for late spring. Traders are watching the next model runs and afternoon observations, which will confirm whether any late-day clearing pushes the peak slightly higher before the market resolves.
