Los Angeles Overnight Lows to Stay Above Average
The National Weather Service (NWS) forecasts overnight low temperatures in Los Angeles on September 27, 2026, to range between 69–70°F (20.5–21.1°C). This is attributed to a persistent marine layer, which brings low clouds and fog, reducing radiational cooling. The marine layer, combined with light southwest winds, is typical for late September in coastal Southern California. These conditions are expected to keep temperatures several degrees above the climatological average low of 62°F (16.7°C). Model consensus supports this forecast, with little variation expected in the coming days.
