Phoenix started Saturday, March 7, 2026, under clear blue skies and a crisp 54°F at Phoenix Sky Harbor, a cool launch to what will turn into a classic warm desert afternoon. Sunshine is set to rule the day, with temperatures climbing into the upper 70s and a forecast high near 79°F. A light east breeze this morning will strengthen later, so patios and outdoor plans should feel comfortably warm, with a bit of a gusty edge at times.
Afternoon Winds Pick Up
By this afternoon, east winds around the Valley are expected to run 5 to 10 mph, with gusts commonly in the 25 to 35 mph range and locally stronger bursts near river corridors and ridgelines. That kind of wind can turn loose canopies, lightweight signage, and umbrellas into unwelcome projectiles, so event organizers and backyard hosts may want to secure anything that is not nailed down. Drivers of high-profile vehicles should use extra caution on exposed stretches of roadway.
Parts of southeast California remain under a Wind Advisory into mid day Saturday, with gusty periods making for choppy conditions if you are out on wide-open routes. Plan to limit time in the most exposed areas where you can, according to the National Weather Service Phoenix.
Sunday And Midweek Heat
Sunday, March 8, 2026, is set to ratchet up the warmth. Highs are forecast near 88°F across much of the Valley, and a few warmer pockets could sneak into the low 90s. A cut-off low parked near Baja may tug some moisture into the region Monday night and Tuesday morning, but the bigger player will be strengthening high pressure by midweek, which should push highs into the low 90s again by Thursday and Friday.
That pattern will keep temperatures running several degrees above normal next week, so it is worth planning outdoor activities for earlier or later in the day when possible, according to the National Weather Service Phoenix.
Monday's Rain Chance
The best shot at measurable rain arrives Monday evening into Tuesday morning, March 9 to 10, mainly across south-central and eastern Arizona and into higher terrain. Scattered showers and a few thunderstorms are on the table, but most locations are expected to pick up only light amounts, generally under a quarter inch. If you have outdoor plans or events Monday night, it is wise to have a backup option in your pocket.
What To Bring
For weekend outdoor plans, sunscreen and plenty of water are must-haves, and it is a good idea to secure or stow lightweight gear if you will be at parks, markets, or other open-air events where the wind can sneak up. Check the latest forecast again before heading out Monday night in case thunderstorm chances increase or the timing of showers shifts.
