A high pressure system is bringing the heat Monday, so much so that a heat advisory will go into effect at 11 a.m. for San Luis Obispo County and the northern portion of Santa Barbara County.

For the beaches, temperatures will range from the 70s to the upper 80s, while the coastal valleys will have a mix of temperatures from the mid-80s to the mid-90s. The inland valley communities will be hot, mostly staying in the mid to upper 90s range. For those who will be spending most of the day outside Monday, it's important to take the necessary actions to be prepared for the hot temperatures.

Northeasterly winds will start out fairly calm Monday, but there's still potential for wind gusts to reach 20-25 miles per hour for the afternoon and shifting out of the northwest. Morning marine layer is likely along the coast and through parts of the coastal valleys, but that is expected to mix out by late morning, making for a sunny afternoon.

What can we expect for the rest of the week? The hot daytime highs are only going to increase for the inland valleys. Triple-digit heat is in the forecast Tuesday and Wednesday before temperatures taper down by a few degrees Thursday. The cooling will continue through Friday, bringing daytime highs closer to seasonal averages.
