Trader consensus on Polymarket has locked in 66-67°F at 100% implied probability for Los Angeles' highest temperature on April 13, backed by verified hourly observations at Los Angeles International Airport (KLAX)—the market's official resolution source via Weather Underground—which peaked at 66°F around 4 PM PDT. National Weather Service data corroborates this, with daytime readings stalled in the mid-60s amid persistent marine layer clouds, onshore flow, and overcast conditions that suppressed solar heating below April climatological norms of about 70°F. Realistic challenges are minimal but could include rare post hoc data revisions from quality control (e.g., sensor recalibration), though no discrepancies have emerged in preliminary NWS climate summaries.
