If you thought February meant mild and comfortable weather in Phoenix, think again. The city is about to experience a major heatwave, pushing temperatures far beyond seasonal norms and possibly into record-breaking territory. While much of the country is still bundling up for winter, Phoenix residents will be dealing with summer-like conditions in the dead of February.
With highs expected to approach 90°F (32°C) or more, meteorologists are urging people to take precautions, stay hydrated, and limit outdoor activities during the peak heat hours.
Current Conditions: The Heat Is Building
Right now, Phoenix is waking up to mild and pleasant conditions, with morning temperatures around 52°F (11°C). But don’t let the cool start fool you—the afternoons are about to heat up fast. The weekend will bring clear skies and climbing temperatures, setting the stage for what could be one of the warmest February stretches in history.
Weekend Forecast: The Heatwave Kicks In
As we head into the weekend, temperatures will steadily rise, getting hotter each day.
- Saturday: Sunny and warm, with a high of 80°F (26°C). The evening will stay mild, with a low of 49°F (10°C).
- Sunday: Even hotter, reaching 83°F (28°C). While this isn’t record-breaking, it’s far above average for February. The night will cool slightly to 50°F (10°C).
Next Week: Record-Breaking Heat Possible
By Monday, Phoenix’s heatwave will be in full effect, bringing highs that could tie or even break historical records.
- Monday: High of 86°F (30°C) and a low of 54°F (12°C). The sun will be intense, and it’s time to start taking heat precautions seriously.
- Tuesday: Temperatures soar to 89°F (32°C), possibly approaching the February record high of 91°F (33°C) set back in 1921. Nights will also stay warm, with lows around 57°F (14°C).
- Wednesday: This could be the hottest day of the heatwave. Phoenix may tie or exceed the all-time February record of 91°F (33°C) set in 1986. With the sun blazing overhead, heat exhaustion becomes a real risk for those spending too much time outdoors.
- Thursday: A slight dip, but still hot, with a high of 89°F (32°C). The nights will also remain unseasonably warm, with lows around 62°F (17°C).
- Friday: The heatwave continues, with temperatures around 87°F (30°C).
Why Is Phoenix Experiencing Such Extreme February Heat?
Phoenix is no stranger to warm winters, but this heatwave is far beyond what’s typical. The culprit? A strong high-pressure system parked over the Southwest, trapping heat and preventing cooler air from moving in.
This setup allows temperatures to climb several degrees above normal, leading to prolonged stretches of heat. While Phoenix often sees warm days in February, temperatures nearing 90°F (32°C) are extremely rare.
What This Means for You—How to Stay Safe in the Heat
- Stay Hydrated: Even though it’s winter, high heat can lead to dehydration quickly. Keep water with you at all times.
- Avoid Outdoor Activities During Peak Heat: The hottest part of the day will be between 12 PM and 4 PM. If you must be outside, wear sunscreen, lightweight clothing, and sunglasses.
- Check on Vulnerable Individuals: Elderly residents, young children, and pets are more susceptible to heat-related illnesses. Ensure they have access to shade and hydration.
- Watch for Signs of Heat Exhaustion: Dizziness, excessive sweating, and nausea are warning signs. If you experience any of these symptoms, move to a cooler place and drink water immediately.
- Expect Increased Energy Usage: With air conditioners running more than usual, energy demand will rise. Be mindful of electricity use to avoid overloading power grids.
Bottom Line: Phoenix Is About to Experience Summer in February
This week’s heatwave is not your typical warm stretch. With temperatures soaring to near-record highs, Phoenix will feel more like May or June than late February.
While it won’t last forever, there’s no significant cooldown in sight. If you love the heat, enjoy it—but stay safe and take the necessary precautions.
