UV index safety and resources

  • Do not burn or tan: Avoid intentional tanning.
  • Seek shade: Get under cover when sun’s rays are strongest between 10 a.m. and 4 p.m.
  • Wear protecting clothing: Long-sleeved shirts and pants, wide-brimmed hat and UV-blocking sunglasses.
  • Generously apply sunscreen: Use a broad spectrum sunscreen with a sun protection factor (SPF) of 30 or higher. Apply sunscreen generously. Apply 15 minutes before going outdoors and reapply every two hours or after swimming, sweating or toweling off.
  • Check the UV index every day: The higher the UV index, the more you should do to protect yourself from the sun. When planning outdoor activities, follow EPA’s safety recommendations.
  • Protect those at risk from UV rays: Children, the elderly and those with special needs may be more sensitive to the sun. Babies younger than six months should be protected from the sun using hats and protective clothing.
