Official observations from the Los Angeles International Airport (KLAX) station, as reported by Weather Underground and National Weather Service data, confirm a maximum temperature of 66°F on May 11, 2026—peaking at 12:53 PM—solidifying trader consensus at 100% implied probability for the 66-67°F outcome. Persistent stratocumulus marine layer, with mist, haze, and low clouds suppressing solar insolation, combined with westerly winds up to 15 mph advecting cool Pacific air, prevented typical daytime warming; temperatures hovered in the low 60s early before a modest midday rise and evening drop to 57°F under fog. This aligns with May climatological norms around 69°F but reflects common "May Gray" variability from cool sea surface temperatures off Southern California. Realistic challenges include minor data revisions in final NWS quality control, though authoritative records rarely shift post-publication.
