Monday is slated to be hot and humid once again as a heat advisory and an extreme heat warning remain in effect for San Diego.

A heat advisory continues for the coast, inland valleys and mountains until 8 p.m. Monday. The extreme heat warning also continues for the deserts until 8 p.m. Monday.

“Make sure to take all the proper heat precautions in this heat. Temperatures will back off, but only slightly, for the next few days before we heat up again,” Chief meteorologist Sheena Parveen said.

A beach hazards statement will continue through Wednesday night for wave heights near 5 to 7 feet and dangerous rip currents.

It will feel less humid later this week, but temperatures will go back up as we approach the weekend. We can expect the weekend to be hot once again as highs will be close to 10 degrees above normal, Parveen said.

Heat advisories are issued when temperatures spike to potentially dangerous levels. San Diego County officials urge people to avoid the heat when possible and use the following tips to stay safe:

Drink plenty of fluids

Stay out of the sun

Wear light, loose-fitting clothing

Avoid using the oven to cook

Limit strenuous activities to early morning or evening

Take refuge in air- conditioned spaces if possible

Check in on potentially at-risk friends, relatives and neighbors
