Verify optimal air conditioner operation. And engine coolant system. Install heater core bypass if not so equipped. We use sunshades year round here.

Summer means high humidity/high heat, and, unlike AZ no cooling in the evening and unlike FL no occasional rain to help the discomfort. A humid desert according to USDA, so the worst of both without the amelioration of either.

Parking in shade, or, short of that, parking with the rear of the car facing the afternoon sun.

As with winter up north one plans outdoor activities to coincide with best daily conditions. Errands, thus, in the earliest morning or late evening. Where work says 8-5 on the site, optimal HVAC operation means less time in cooling to a lower humidity and cooler temp.

The tricks to keep the interior from overheating are worth the trouble, especially as old folks, children and pets are susceptible to heat prostration. So a plan (where & when) is always best and easily met by optimal routing.
