Recommendation
Drive in the morning between 7 AM and 10 AM when temperatures are 83-90F, before the peak heat. In the evening, the best window is about 9 PM to 11 PM, when it has cooled to the upper 80s, but watch for showers (22-26% chance). Avoid the 12 PM to 7 PM heat peak and storm risk if possible. Check coolant, tires, and A/C beforehand, carry water, and never leave people or pets in a parked car.
