Here are some ways to prepare as record-breaking March heat hits the Bay Area

SAN FRANCISCO (KGO) — The Bay Area is preparing for an unusually hot week, with record high temperatures expected to begin Monday and a heat advisory in effect through Friday.

Officials are urging residents to stay hydrated and take precautions during what some are calling an unprecedented March heat wave.

Beaches and running paths at Crissy Field were crowded Sunday as temperatures in San Francisco felt more like late summer.

“Can you believe this is March?” said Logan Mendenhall of San Francisco. “I can’t. I have family in NYC – they’re experiencing blizzard after blizzard. We’re sitting in 80 degrees, amazing.”

Mendenhall and friend Gianstelvio Radesich were out for a run and said they plan to keep exercising despite the forecast. “I’m definitely running this week, even if it’s 100 degrees,” Radesich said.

San Francisco Fire Department Capt. Jack Ayers called the conditions “an unprecedented heat wave” and warned beachgoers about hazardous sneaker waves and rip currents.

“We do not have lifeguards on duty 24 hours a day at our beaches at Ocean Beach, Baker Beach, China Beach, and Fort Point. If you do choose a beach, view it from a distance,” Ayers said.

The Santa Rosa Fire Department posted reminders on social media to stay hydrated and never leave children or pets unattended in vehicles.

PG&E is advising customers to conserve energy by opening doors and windows in the morning, then closing drapes or shades in the afternoon.

“Another thing you can do to save energy is set your thermostat to 78 degrees if you’re home, 85 when you’re leaving,” said PG&E spokesperson Megan McFarland. “It’s definitely higher than normal, but it can help cut down your energy bills during a heat wave like this.”

The heat advisory remains in effect for the Bay Area through Friday.
