Coastal San Diego UV Reflection: Why La Jolla, Coronado & PB Drivers Need Stronger Tint

Key Takeaway

NOAA and Scripps Institution of Oceanography research shows that ocean and sand surfaces reflect 10 to 25 percent of incident UV radiation, increasing total UV exposure for drivers along the San Diego coast. Coastal San Diego cities including La Jolla, Coronado, Pacific Beach, and Del Mar see elevated effective UV index readings.

If you drive along Pacific Coast Highway, the Strand, or Torrey Pines daily, your effective UV exposure is meaningfully higher than inland drivers — here's the science with citations.
