IS A WARM CUP

March 12, 2026 11:56 am

Southern California Overview:

  • Strengthening high pressure aloft and weak offshore flow will bring near-record high temperatures to much of southwestern California today and inland from the coast on Friday. Onshore flow for the weekend will bring some cooling for the coast into the valleys but with high temperatures remaining well above average. For next week, stronger high pressure aloft will bring additional warming for inland areas with record or near-record heat for March for much of next week. Widespread moderate or greater Heat Risk is expected for much of next week beginning on Monday for the valleys, inland Orange County, and the lower deserts with heat-related illnesses likely for sensitive populations.
