A wind advisory remains in place for the south coast, mountains, and foothills across Santa Barbara County through 6 a.m. Wednesday morning as winds continue to gust near 40 miles per hour for cities like Montecito. After the advisory expires, most winds near and around the south coast will begin to calm down, but San Luis Obispo County will have some gusty conditions develop throughout the afternoon.
Coming off what was already a warm morning with temperatures in the 70s across coastal valleys and beaches, the warming only continues heading into the afternoon. Daytime highs across the beaches and valley locations will range from the upper 80s to the upper 90s. Even Pismo Beach is expected to reach the upper 90s Wednesday as parts of the north coast hang on to the 70s and 80s. The northeast flow will be slightly stronger Wednesday, which is why temperatures are trending up slightly, however, by Thursday that flow should weaken and bring coastal temperatures down by a few degrees again.
In terms of a cooldown, most models are suggesting that will happen by Sunday when some regions begin to return to normal daytime averages, Before the cooling begins, both San Luis Obispo and Santa Barbara Counties will remain under a heat advisory through Friday night.
