Recommendation
Safer driving windows: morning 7:00–10:00 AM before the worst heat builds; evening 8:00–10:00 PM when temperatures are lower, but watch for isolated thunderstorms. Avoid unnecessary trips during the peak heat from about 12:00–6:00 PM, and do not leave children, pets, or vulnerable passengers in parked vehicles.
