Sorry, folks. The heat is returning to San Diego County. Nevermind that it's fall or that it's October.
A high pressure system over California, combined with offshore flow, will bring hot daytime weather to the county later this week, with inland temperatures soaring into the triple digits, forecasters said Wednesday.
The hottest temperatures will occur from mid-morning to late afternoon Friday and Saturday in coastal areas; from late morning to late afternoon Friday through Sunday in the valleys; and from late morning through late afternoon Friday and Saturday in the mountains, according to the National Weather Service.
The agency scheduled a heat advisory for coastal and mountain areas from 11 a.m. Friday to 8 p.m. Saturday and a heat advisory for the valleys from 11 a.m. Friday to 8 p.m. Sunday.
There was no advisory issued for the deserts, though triple-digit heat is also expected there starting Friday.
"Heat can be stressful to animals and humans, making it hard for the body to acclimate and remain hydrated," according to the weather service. "Without precautions, even healthy adults could experience heat stress and illness."
The agency encouraged those spending time outside to reschedule strenuous activities to early morning or evening hours, if possible.
A slow cooling is expected early next week. Maybe then it will feel like fall.
