Los Angeles Overnight Low Expected at 70-71°F
Persistent marine layer and onshore southwesterly flow are limiting overnight radiational cooling across the Los Angeles basin. Official National Weather Service forecasts indicate a Sunday night low temperature in the mid-to-upper 60s, with a strong consensus around 70-71°F (21-22°C). This aligns with typical late-September coastal climatology under weak pressure gradients. Morning low clouds, fog, and dew points near 67°F (19°C) are contributing to the limited cooling, with current readings in the mid-70s (23-24°C). While this setup deviates slightly from the average lows of 62°F (17°C) for this time of year, model consensus suggests minimal further decline before midnight.
