Wednesday, April 29, 2026 — Phoenix rolled into the day with a mild 66°F (19°C) start and is headed for a high near 89°F under mostly sunny skies. With low humidity and light south breezes, the air will feel very dry, and temperatures are still on course to slide into the lower 90s by Friday, with mid‑90s expected across the Valley this weekend.
What To Expect Today
According to the National Weather Service in Phoenix, today brings mostly sunny skies, a high near 89°F, and gentle south winds around 0–5 mph. Afternoon relative humidity is expected to drop into the single digits to teens (roughly 8–15%), and tonight the low should land near 66°F as cloud cover increases overnight.
Thursday And Rain Chances
The next weather system is forecast to track just to the south, so most of the wet weather should skip metro Phoenix. Forecasters keep only a slight chance for light showers in play for portions of southeast Arizona and higher terrain on Thursday. Across the Valley, rain chances stay minimal, and any showers that manage to pop up are likely to be brief and spotty.
Weekend Outlook And Fire Weather
Temperatures climb into the end of the week with highs near 92°F on Friday, then roughly 95–96°F for both Saturday and Sunday. Southeasterly winds should run around 5–10 mph, with gusts up to about 25 mph possible on Sunday. The mix of low humidity and those afternoon gusts could bring elevated fire‑weather conditions in some spots, so it is a good time to secure loose outdoor items and skip open burns if you can.
Stay Cool And Prepared
Stay ahead of the heat by drinking plenty of water, easing up on strenuous outdoor plans during the hottest part of the day, and making sure pets are shaded or brought indoors when temperatures peak. If you need air‑conditioned relief, the City of Phoenix cooling centers and Heat Relief Network list available locations and hours.
