Tucson, Arizona – Father’s Day weekend plans may need a major adjustment as southern Arizona braces for a punishing stretch of extreme heat, with triple-digit highs expected through early next week.
An Extreme Heat Warning remains in effect for Tucson and surrounding areas from 10 a.m. Saturday through 8 p.m. Monday, according to the National Weather Service in Tucson. Daytime highs may reach a blistering 111°F on Sunday, with Saturday and Monday peaking near 108°F and 109°F, respectively.
Hotspots include Tucson Metro, Gila River Valley, I-10, and western and central Pima County, including the Tohono O’odham Nation. Heat-related illnesses are expected to increase significantly, especially between 2 p.m. and 6 p.m. — the hottest part of each day.
Authorities urge residents to limit outdoor activity, stay in air-conditioned environments, and check on vulnerable neighbors and pets. Never leave children or animals in vehicles — interiors can reach lethal temperatures within minutes.
Workers and outdoor recreationists are advised to wear light clothing, drink water frequently, and avoid midday exertion. Cooling centers may be available; local officials recommend visiting city websites for location details.
This heat wave rivals previous June records, with humidity levels below 15%, increasing dehydration risks. Anyone experiencing signs of heat exhaustion — such as dizziness, nausea, or confusion — should seek shade and medical help immediately.
⚠️ More heat alerts are possible if conditions persist into midweek.
