It is going to be a hot week for the Central Coast as heat advisories go into effect for San Luis Obispo and Santa Barbara Counties.
For San Luis Obispo County, the advisory will remain in place through Wednesday night. During this time, northeast flow will keep daytime highs from the 80s to low 100s. For perspective, San Luis Obispo could reach 100 degrees Monday, which is four degrees above the record that was set in 2014. Even for local beaches, maximum temperatures will climb to the 80s and 90s. In Santa Barbara County, the mountains and foothills will remain under the advisory through Friday at 5:00 p.m. as daytime highs stay between the 90s and triple-digits. As a reminder, it's important to stay hydrated by drinking plenty of water, stay in shaded areas, and check on neighbors, relatives, and pets.
As northeast flow becomes slightly weaker Tuesday, daytime highs will trend down slightly. This means that valley locations will return to the low to mid-90s instead of being closer to the low 100s. The warmer weather is expected to last through the weekend, but the return of the marine layer will likely be back in the forecast for the coastline by Thursday.
