Official National Weather Service observations from Los Angeles International Airport (KLAX)—the resolution authority for this market—confirm the highest temperature on May 13, 2026, fell within 68-69°F, driving the 99.7% trader consensus on that outcome backed by substantial trading volume. This aligns with persistent marine layer clouds and strong onshore flow, which capped daytime heating below the typical mid-May average of around 72°F, as indicated by recent Automated Surface Observing System (ASOS) data and preceding daily summaries showing similar subdued highs like 67°F on May 12. Model consensus from NOAA had anticipated this cool pattern shift starting May 10. Realistic challenges are minimal but could include rare post hoc data quality revisions by NWS, though such adjustments occur infrequently for established records.
