Phoenix is trading in its winter chill for T-shirt weather today, January 28, as sunny, dry, and mild conditions settle over the Valley. Afternoon highs are expected to top out near 75°F across the lower valley under mostly sunny skies, easing back into the low 70s later in the day. Tonight, look for a low near 47°F with partly cloudy skies hanging around after dark.
Afternoon Breezes, Where To Watch For Gusts
Winds stay on the gentle side today, generally out of the northeast at about 0 to 5 mph. The one wrinkle comes Thursday and Friday, January 29 and 30, 2026, when a brief uptick in gusts is expected across higher ridgelines and the Lower Colorado River Valley. In those spots, periodic gusts could reach 20 to 25 mph, so it is a good idea to secure loose patio furniture if you are headed for the foothills or river corridors, according to the National Weather Service.
Weekend Outlook
By the weekend, a building ridge will nudge temperatures even higher, with afternoon highs flirting with 80°F on Saturday, January 31, and Sunday, February 1. Rain chances stay essentially at zero through early next week. Local forecasters have also pointed out how unusually warm January has been for the Valley, a trend highlighted by ABC15.
What This Means For You
The stretch of warm, dry weather is a gift for outdoor plans, but it comes with a catch: low afternoon humidity, often in the 10 to 20 percent range, and modest fire-weather concerns in brushy areas near the foothills. If you are spending long hours outside, keep the water bottle handy, use sun protection, and avoid recreational or agricultural burning until humidity improves overnight.
Travel and Flights
For travelers, it is smooth sailing. No major travel or flight disruptions are expected through Wednesday night, with aviation forecasts calling for normal operations at Phoenix Sky Harbor under occasional high clouds. Drivers can expect dry roads and good visibility for the evening commute.
