TUCSON, Ariz. – Drivers across southern Arizona should prepare for another stretch of dangerous heat as October opens with near-record highs. By Wednesday, temperatures in Tucson will climb to 96 degrees, pushing heat safety concerns across the city and along I-10. Residents are urged to limit outdoor activity in the afternoon and stay hydrated as the late-season heat persists.
According to the National Weather Service in Tucson, Monday starts warm with highs near 92 before conditions trend hotter each afternoon. Tuesday will reach 94 degrees, and by Wednesday the mercury peaks at 96, approaching October records. Officials caution that vehicles parked in direct sunlight can reach life-threatening heat levels in minutes, making extra care vital for children and pets.
The persistent dry air means little relief at night, with lows only falling into the upper 60s and lower 70s. Winds will remain light and variable, keeping the region under clear skies and amplifying sun exposure during the day. Those traveling on I-10 and State Route 77 should carry extra water, especially during midday commutes.
Tucson Electric Power reminds customers to monitor energy usage during peak hours, as cooling demands remain high into midweek. Outdoor workers should schedule tasks in early morning or late evening hours when heat stress is less severe.
Relief comes slowly. By Saturday, highs are expected to dip closer to 87 degrees, a noticeable break after several scorching days. Until then, warnings remain in place for heat illness and fire danger due to low humidity.
