Recent forecasts from the National Weather Service and local models indicate overnight lows in the upper 60s to low 70s across Los Angeles stations on August 22, consistent with the closely bunched market probabilities centered on 66–71°F. Persistent marine layer influence and moderate onshore flow from the Pacific are limiting radiational cooling overnight, a typical late-summer pattern that keeps minimums well above historical extremes near 52°F. Recent climatological data show daily lows averaging 65–68°F at LAX and downtown sites, with minimal day-to-day variability under stable high pressure. Traders appear to weigh small differences in forecast model runs and exact station resolution criteria, as the lowest reading can vary by a degree or two depending on whether the low occurs before or after dawn and on local topography. Updated NHC and NWS guidance through the morning will likely refine the final observed minimum.
