Introduction to Summer-like Temperatures
A strong ridge of high pressure is moving into the region, bringing well above-average temperatures throughout the week.
A prolonged heat wave will take hold starting Monday, pushing highs into the triple digits in some inland areas by the middle of the week.
The hottest days are expected to be Wednesday and Thursday, with inland areas expected to reach 95–103°F.
Overnight temperatures will also remain unusually warm, and heat advisories may be issued.
Heat Wave Details
A cooling trend is expected to begin Friday, as the marine layer gradually returns. This will help bring temperatures closer to seasonal averages by the weekend, along with an increase in the marine layer.
A high-pressure ridge built over the region Sunday, triggering a steady warming trend.
“Next week is going to be a hot one and lasting at least two days longer than the previous heat wave,” the NWS stated.
Temperatures across most areas are forecast to climb another 5 to 10 degrees by Monday afternoon. The western San Fernando Valley could near 90 degrees, up to 15 degrees warmer than Sunday.
Starting Tuesday, highs are expected to mirror the September-October heat waves, reaching the low 100s in the warmest valleys, the low 90s in downtown Los Angeles and the 80s in most other areas away from the coast, according to forecasters.
The conditions could warrant another round of heat advisories for the coastal valleys and possibly even parts of the interior coastal plain, according to the NWS.
Onshore flow is expected to return Thursday, bringing a gradual cooling trend heading into next weekend.
Heat Health Safety Tips
To stay safe during the heat wave, consider the following tips:
- 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!
