What to Know

  • Temperatures are increasing this week, and will be in the triple digits from Tuesday into Sunday in some areas.
  • An excessive heat watch is in place almost everywhere in SoCal from Wednesday morning into Sunday evening.
  • Stay hydrated, practice good heat safety, and watch for signs of heat-related illness.

It's late summer in Southern California, and that means temperatures are high -- especially this week.

With temperatures in the high 90s on Monday, it's set to be the coolest day all week long, with a brutal heat wave keeping weather in the triple digits in the valleys, Inland Empire and the deserts.

An excessive heat watch is in place over almost all of Southern California from Wednesday onwards.

"We've got a widespread heat wave headed our way," NBC4 meteorologist Belen De Leon said.

"This is going to be several days where we need to have our guard up and practice good heat safety," she said.

High temperatures bring an elevated risk of heat illness.

Heat illness can come in two forms: heat exhaustion, and the more extreme heat stroke.

Heat exhaustion symptoms include heavy sweating and a rapid pulse. If you feel yourself coming down with heat exhaustion, get to air conditioning quickly and drink lots of water to stay hydrated.

Heat stroke is what happens when heat exhaustion is not treated. People experiencing heat stroke stop sweating entirely, and may lose consciousness. Seek help immediately by calling 911 if you or someone you know is experiencing heat stroke.

Here are some tips to avoid heat-related illnesses:

  • Stay hydrated! The more hydrated you are, the more effective your body will be at keeping you cool. Drink water – not fizzy and alcoholic drinks, which will dehydrate you.
  • Avoid exercise in the middle of the day. If you need to exercise outside, do it early in the morning when the temperature is lower.
  • Wear lightweight, light-colored natural fabrics like cotton and linen, as these will help your skin breathe and let your sweat evaporate, cooling you down.
  • We sweat around half a pint daily from both feet (and we wonder why they stink!), so if you can, wear sandals or flip-flops to let your foot sweat evaporate.
  • Use a fan to circulate air from open windows. Keep your blinds or curtains drawn during the day, so your home doesn’t heat up while you’re out. Turn off big appliances and help prevent brown-outs!
  • To cool down quickly, run your wrists under a cold tap or keep a water spray in the fridge for a quick cooling spritz to the face.
  • Keep some wet wipes in your bag so you can freshen up your hands, face and neck if you get hot or clammy.
  • Want to stay cool at night? One way is to wash your feet in cool water or take a cold shower before bedtime – especially if you get hot during the night or have hot sweats.
  • To cool down in bed, try keeping your pillowcase or sheets in a plastic bag in the fridge during the day. Put them back on the bed at night. The fabric will stay cool when you’re trying to get to sleep.
  • And bring your pets in and make sure they have shade and water.
  • Be prepared for power outages and know where cooling centers are!

The excessive heat warning starts Wednesday morning and ends Sunday evening.
