PHOENIX — Temperatures are sizzling across Arizona!

Thursday marked the hottest day ever recorded in the month of August in Phoenix with a scorching high of 118 degrees.

The previous record for the month of August was 117 degrees, which we hit several times.

This also marked a new daily heat record, breaking the old record of 112 from 2012.

We will drop several degrees on Friday, but our Extreme Heat Warning remains in effect through 8 p.m. Friday as temperatures continue to sizzle.

We remain in ABC15 Weather Action mode too as a reminder to take action to protect yourself, your loved ones and your pets.

Make sure to stay hydrated throughout the day. Try to avoid being outside between 10 a.m. and 6 p.m. If you have pets, keep them indoors as much as possible. If you absolutely have to be outdoors for work or any other reason, take frequent breaks in the shade and drink water regularly.

Be careful around hot surfaces too. Car doors, steering wheels and playground equipment can cause serious burns after just a few seconds in this kind of heat.

There is still a little monsoon moisture hanging over southern and eastern Arizona, which could lead to isolated storms in those areas.

For the Valley, our forecast is looking mostly dry, but there is a slight chance of an isolated storm or two over the weekend as temperatures continue to top 110 degrees.

2025 Sky Harbor Official Rainfall to date: 1.63" (-2.44" from average)

Monsoon 2025 Sky Harbor Official Rainfall: 0.16" (-0.96" from average)
