California summers can be brutal on your vehicle. With temperatures often exceeding 90°F (and interior temps reaching 140°F+), your car faces serious challenges from intense UV rays, heat, and oxidation.

Here's how to protect your vehicle and keep it looking great through the hottest months of the year.

California Summer Stats

  • • Average summer temps: 85-100°F+
  • • Interior car temperature: Up to 140°F in direct sunlight
  • • UV Index: 9-11 (Very High to Extreme)
  • • Dashboard temperature: Can exceed 180°F

Protecting Your Exterior Paint

1. Apply Quality Protection Before Summer Hits

Get your car detailed with a ceramic coating or quality wax in late spring. This creates a protective barrier against UV rays, oxidation, and heat damage.

Pro Tip: Ceramic coating lasts longer and provides superior heat and UV protection compared to traditional wax.

2. Wash Regularly (But Smartly)

Summer dust, tree sap, and bird droppings can bake onto your paint in the heat. Wash your car every 1-2 weeks, but avoid washing in direct sunlight or when the surface is hot to prevent water spots.

Best Time: Early morning or evening when temperatures are cooler.

3. Park in the Shade Whenever Possible

Direct sunlight accelerates paint fading and clear coat damage. Park under cover, use a car cover, or seek tree shade to minimize UV exposure.

Note: Be careful parking under trees with sap – it can damage paint if left too long in the heat.

Protecting Your Interior

Use a Windshield Sunshade

A reflective sunshade can reduce interior temperature by 20-30°F and prevent dashboard cracking and fading. They're inexpensive and highly effective.

Condition Leather & Vinyl Surfaces

Heat causes leather and vinyl to crack and fade. Apply a UV protectant conditioner monthly to keep surfaces supple and protected.

Focus Areas: Dashboard, steering wheel, door panels, and seats.

Consider Window Tinting

Quality window tint blocks up to 99% of UV rays and can reduce interior heat by 60%. It protects both you and your car's interior from sun damage.

Mechanical Considerations

While we focus on detailing, don't forget these important summer maintenance tasks:

  • Check coolant levels – Essential for preventing overheating
  • Test A/C system – Make sure it's working before you need it
  • Inspect tire pressure – Heat causes pressure to increase; check weekly
  • Replace cabin air filter – Improves A/C efficiency and air quality

Your Summer Car Care Checklist
