Dangerous Heat Headed For Phoenix: Potential Record-Breaking Temps

PHOENIX, AZ — The Valley's first wave of extreme, dangerous heat in 2022 is expected to hit Wednesday, according to the National Weather Service.

With a high of around 108 on Wednesday, peak temperatures are expected to continue rising each day for the rest of the week, reaching 113 on Saturday. And nighttime lows during that time aren't expected to give much relief, expected to be in the low 80s on Wednesday and reaching the mid-80s by the weekend.

The National Weather Service has issued an excessive heat watch for Wednesday morning through Monday evening, with the hottest temperatures expected Saturday and Sunday afternoon.

It's possible that the Valley could see record breaking high and low temperatures.

The weather service warns of a very high heat risk during that time with the possibility of heat related illnesses, "including heat cramps, heat exhaustion, and heat stroke" which can be fatal.

The weather service advises staying inside in air-conditioned buildings, staying hydrated and not leaving kids or pets unattended in cars.

It's also recommended to check in on those particularly vulnerable to the heat, including young children and the elderly.

There are public emergency cooling stations and water distribution sites available across Maricopa County for those who don't have access to air conditioning.

According to the weather service, early signs of heat related illness include thirst and muscle cramps. Signs of heat exhaustion include cool, moist, pale skin; headache; dizziness; weakness or exhaustion and nausea. Signs of heat stroke include: vomiting; confusion; throbbing headache; decreased alertness or loss of consciousness; high body temperature; hot, dry skin; rapid, weak pulse; rapid, shallow breathing and seizures.

If you or someone else has signs of heat stroke, you should call 911, because it can be deadly, the weather service advised.
