Official observations from Los Angeles International Airport (KLAX) recorded a daily maximum of exactly 70-71°F on May 31, locking in the market’s near-certain outcome. Persistent onshore flow and a stable marine layer suppressed daytime heating under partly cloudy skies, preventing the upper-70s to low-80s readings projected by earlier model runs. This outcome sits near the lower end of late-May climatological norms for the basin. A revised National Weather Service climatological report or station data correction could theoretically shift resolution, though such adjustments remain rare once preliminary readings are confirmed.
