Inland valleys (Paso Robles) temperatures will reach the mid-90s, while the coastal valleys (San Luis Obispo) will range between the high 70s and low 80s. The beaches will warm up to the 60s, except for Cayucos, Avila Beach and Shell Beach, which will reach the high 70s and perhaps even the low 80s through Labor Day.
