Recent National Weather Service and model guidance indicate Los Angeles overnight lows for October 9 will likely fall in the mid-to-upper 60s as the late-season heat dome weakens and onshore flow increases. The preceding multi-day extreme heat episode, with multiple 100°F+ readings downtown, has delayed typical seasonal cooling, leaving marine layer development and timing as the key variables that could push the minimum a few degrees lower or keep it nearer 70°F. Ensemble spread remains modest but widens with forecast horizon, supporting closely matched market-implied probabilities across the 60–77°F bins while limiting odds on sub-60°F or 78°F+ outcomes. Updated NHC and local office briefings on October 8 will provide the next high-resolution data points.
