Official observations at Los Angeles International Airport (KLAX) confirm the highest temperature on March 28, 2026, reached just 66°F, per Weather Underground historical data—the standard source for such prediction markets—driving trader consensus to 100% on "67°F or below." This outcome stems from a sharp cooldown after mid-March's historic heat wave, which shattered records with downtown LA highs over 90°F amid a ridge-amplified pattern; by late month, persistent marine layer stratus clouds and cool onshore flow from the Pacific suppressed daytime heating, keeping conditions mostly cloudy with averages near 62°F. Scenarios challenging this include rare post hoc data revisions by NOAA quality control, though NWS preliminary summaries align closely at 68°F maximum—still market-irrelevant—and no further updates are expected before resolution.
