Arizona Weather Alert: Triple-Digit Temps Are Back, and Just in Time to Ruin Your Weekend

If you’re planning a long weekend packed with pool parties, backyard grilling, or outdoor adventures, you might want to take a second look at the forecast. An Arizona Weather Alert has been issued, and it’s not just another warm spring weekend—it’s the start of serious heat.

Forecasters are calling for a high of 98°F in Phoenix on Saturday, with Sunday staying just as hot. And by Memorial Day Monday, triple-digit temperatures are expected to make their official return. It’s the kind of heat that creeps up quickly, turning casual outdoor fun into a real health risk if you’re not prepared.

Arizona Weather Alert: Why You Should Take This Weekend’s Heat Seriously

Yes, it’s Arizona—and yes, it gets hot. But this early surge in summer-like temperatures is still a big deal. Normally, Phoenix hits the 100-degree mark in early May, but this year, the city nearly reached that point as early as March. Now, as we head into a holiday weekend, we’re staring down highs in the upper 90s and beyond.

This Arizona Weather Alert isn’t just about the numbers—it’s about the impact. High heat puts extra strain on your body, your car, and your plans. Whether you’re hiking Camelback Mountain, hosting friends for a barbecue, or just running errands, that kind of heat can take a toll fast.

What You Can Do to Stay Safe

With heat this intense, preparation is key:

• Hydrate constantly, even if you’re just lounging around.

• Plan your outdoor activities early in the day or after sunset.

• Wear light, breathable clothing and use sunscreen.

• Check on your neighbors, pets, and anyone without AC.

• Never leave anyone in a parked car, even for a minute.

Memorial Day weekend is supposed to be a time to relax and recharge—but with extreme heat setting in early this year, being smart about the weather could make all the difference. Don’t let high temps sneak up on you.

FAQ About Arizona Weather

1. How hot will it actually get in Phoenix this Memorial Day weekend?

Phoenix is expected to reach 98°F on Saturday and Sunday, with temperatures pushing 100°F or higher by Memorial Day Monday. It’s shaping up to be one of the earliest heat waves of the season, so it’s a good time to start treating your outdoor plans like it’s already mid-summer.

2. Is this kind of heat normal for this time of year in Arizona?

Kind of—but it’s still early. Phoenix usually sees its first 100-degree day around May 11, so this isn’t unheard of. That said, hitting the high 90s and beyond for multiple days in a row this early is a clear sign that summer is coming in strong and fast this year.

3. How can I stay safe if I have outdoor plans this weekend?

Hydrate often, dress in light-colored clothing, and avoid being outside during the hottest part of the day (10 a.m. to 4 p.m.). If you’re hiking or grilling, try to do it early in the morning or in the evening. And don’t forget to wear sunscreen—UV levels can be intense even if it’s partly cloudy.

4. Who’s most at risk during a heat wave like this?

Children, older adults, and anyone with pre-existing health conditions are especially vulnerable. Pets, too! Be sure they have access to shade, water, and cool areas—and never leave anyone in a parked car, not even for a short time.

5. Where can I find up-to-date weather alerts and safety tips?

Check trusted sources like the National Weather Service, ABC15 Arizona, or your favorite weather app. They’ll keep you updated with the latest temperatures, alerts, and recommendations. You can also sign up for local emergency text alerts to get real-time updates on any developing heat-related risks.
