Sunshine is already doing its thing over Phoenix on Wednesday, February 25, with a mild start near 61°F at Sky Harbor. That comfort window will not last long. Temperatures are set to jump quickly, with today's high near 87°F, and forecasters say the real sizzle shows up late this week. Expect a stretch of upper 80s and low 90s that will make midweek baseball games and afternoon errands feel a lot more like spring than late February.
Record Watch
An unseasonably strong ridge of high pressure is on track to push lower desert highs into the upper 80s and low 90s from Thursday through early next week. Forecasts call for a high near 90°F on Thursday and highs around 93°F Friday through Sunday. Overnight lows will stay unusually warm, mostly in the upper 50s to low 60s, which means less of the usual nighttime cool-down.
Temperatures will run about 15 to 20 degrees above normal, giving Phoenix a solid shot at tying or breaking daily record highs and warm overnight lows from Thursday through Monday. For now, there are no watches or warnings posted for the Phoenix area, according to the National Weather Service Phoenix.
What This Means For Your Plans
The hottest part of each day will land roughly between 2 p.m. and 5 p.m., so outdoor workouts, yard projects, and long walks are better saved for morning or evening. Bring water for any outside time, even if it “doesn’t feel that bad yet.” Outdoor workers, older adults, and infants should take extra breaks and stick to the shade during peak sun, and pets will need shorter walks plus plenty of water in a cool spot. Winds should stay light most days, so the heat will come from clear skies and strong sun rather than gusty conditions.
Local Resources
The City of Phoenix operates a Heat Relief Network with cooling centers and hydration stations across the area. A 24/7 heat respite site is open downtown at 20 W Jackson St, and many libraries and recreation centers keep extended hours during hot stretches. For detailed locations and hours, check the City of Phoenix. If you or a neighbor depend heavily on air conditioning at home, it may be worth looking into energy assistance programs now, before this warm spell really settles in.
Outlook
The high pressure ridge is expected to weaken by the middle of next week, allowing temperatures to drift back toward typical late February and early March levels, although readings will likely stay a few degrees above average through at least midweek. For now, treat Thursday through Sunday as a bona fide warm stretch and use your usual summer-style heat precautions when you head outside.
