Morning temperatures across the Central Coast were clocking in around the upper 60s just before 4:30 Tuesday morning, which sets the tone for how the rest of the day will play out. Offshore flow will continue to be a factor in the forecast, which means a hot afternoon for the region.
A heat advisory will go into effect at 10 a.m. for San Luis Obispo and Santa Barbara Counties and expire at 5:00 p.m. The beaches will range from the upper 80s to the low 90s Tuesday, but the average temperature around this time of the year is closer to the upper 60s. The coastal valleys and inland valleys actually won't be much warmer with peak temperatures from the low to upper 90s. As a reminder, it's important to drink plenty of water, stay in shaded areas and air conditioned rooms, and check on neighbors and relatives.
Northwesterly winds will be fairly moderate throughout the afternoon, ranging from 15-25 miles per hour at their peak.
