Official National Weather Service observations confirm the highest temperature at Los Angeles International Airport (KLAX) ASOS station reached 70°F on April 20, 2026, per the daily climate summary and Weather Underground records, driving 100% trader consensus for the 70-71°F outcome on Polymarket. This aligns with pre-event NOAA forecast model consensus predicting mild highs in the upper 60s to low 70s, influenced by persistent marine layer, cool onshore flow, and overcast skies that capped daytime heating—conditions typical for coastal Southern California in spring amid neutral ENSO patterns. Historical April averages hover around 69-71°F at KLAX, reinforcing the positioning. Realistic challenges include rare post-validation data corrections from automated sensors, though ASOS quality controls make revisions improbable; final resolution awaits Wunderground confirmation.
