Official National Weather Service observations from the Automated Surface Observing System at Los Angeles International Airport (KLAX) confirm the highest temperature on May 12, 2026, reached 66-67°F around midday, aligning with near-unanimous trader consensus at 100% implied probability for that bin. Persistent marine layer stratus clouds under overcast skies (OVC020), driven by strong onshore southwest winds of 10-15 mph and cool air advection from a weakening upper-level high-pressure ridge, suppressed daytime heating well below the mid-May climatological average of 70°F at KLAX. National Hurricane Center—no, NWS forecasts accurately anticipated this amid typical "May Gray" conditions in coastal Southern California. Only a rare revision in final climatological reports could challenge this positioning, as preliminary hourly data shows no higher peaks.
