San Diego County is in the grip of a heat wave that’s expected to last all week, forecasters said Sunday.

A heat advisory is in effect from 10 a.m. Tuesday to 8 p.m. Friday for the coastal areas. A heat advisory is in effect until 10 a.m. Tuesday, then an extreme heat warning is in effect from 10 a.m. Tuesday to 8 p.m. Friday for the mountains and valleys. Plus, an extreme heat warning is in effect until 8 p.m. Friday for the deserts.

Widespread moderate to locally major heat risk is expected for the coast, valleys and mountains except near the beaches and for the higher elevations in the mountains, with major to extreme heat risk for the lower deserts.

Temperatures are on track to peak Tuesday through Thursday, generally 8 to 12 degrees above average, according to forecasters.

Downtown San Diego reached 86 degrees on Sunday, and was expected to climb to 88 by Thursday. In the county’s desert area, Borrego Springs reached 112 on Sunday, and could hit 114 by Wednesday, according to the NWS.

Inland highs will range from 95 to 107 degrees this week, with nighttime lows only dropping to the mid-70s. The low deserts are consistently expected to see highs of 110-115 degrees Tuesday through Friday, along with major to extreme heat risk, the NWS said.

While highs in coastal areas will mainly remain below 90 degrees, overnight temperatures will not drop below the lower 70s, which will especially affect those without access to air conditioning.

Above-average high and low temperatures will continue through next week, according to the NWS.

How to Stay Cool on Hot Days

Cool Zones are open throughout San Diego County and can help keep San Diegans cool. “Cool zones” are free air-conditioned sites where people can gather to beat the heat together.

If you can’t make it to a cool zone, HHSA has other tips for people, particularly older adults, to stay cool on hot days. The agency recommends:

• Avoiding physical activity during the day and pacing yourself. Instead, plan your exercise between 4 and 7 a.m., typically the coolest part of the day.
• Staying indoors as much as possible. The coolest floors are the lowest floors. Keep your shades and blinds closed as much as possible with your windows slightly open.
• Taking a cold shower.
• Wearing lightweight, light-colored and loose clothes.
• Never leaving children or pets inside vehicles, even with the windows cracked.
• Drinking more fluids than usual. Water is best and alcohol or caffeine can make the heat’s effects worse.
