Phoenix, Arizona – Arizona is on heat watch as dangerously high temperatures are set to return to the Phoenix metro Monday, July 28, with highs soaring to 111°F by late afternoon — one of the hottest days this summer. Residents are urged to limit outdoor activity, especially along the I-10 corridor, and stay indoors between 1 and 5 p.m. when the sun’s intensity peaks.
According to the National Weather Service in Phoenix, Monday will be sunny and hot with light west winds shifting southeast by evening. Heat index values will push the “feels like” temperature near 115°F. Monday night stays stifling, with lows only dipping to 86°F under mostly clear skies.
This extreme heat puts added strain on power systems, increases wildfire risk, and threatens public health — especially for seniors, children, and those without reliable air conditioning. Stay hydrated, avoid strenuous activities, and check on vulnerable neighbors.
