UV Index

The UV Index provides a daily forecast of the expected intensity of ultraviolet (UV) radiation from the sun. Some exposure to sunlight is enjoyable. However, too much sun can be dangerous. Overexposure to the sun's ultraviolet radiation can cause immediate damage, such as sunburn, and long-term problems, such as skin cancer and cataracts.

It is important to remember that people of all skin types need to be protected from overexposure to the sun. Overexposure to UV radiation poses the risk of serious health effects for everyone, but not everyone is equally at risk. For example, you may be at greater risk of contracting skin cancer if your skin always burns; if you have blond or red hair; or blue, green, or gray eyes. Other factors indicating an increased risk of skin cancer include: a history of blistering sunburns in early childhood, the presence of many moles, or a family history of skin cancer. However, it is a good idea to remember that all people, no matter what skin type, are equally at risk of eye damage. So remember to be SunWise!

Below are some additional steps you can take to be SunWise
Minimal
  • People with very sensitive skin and infants should always be protected from prolonged sun exposure.
0 to 2
Low
  • Wear a hat with a wide brim and sunglasses to protect your eyes.
  • Use a sunscreen with an SPF of at least 15 and wear long-sleeved shirts and long pants when outdoors.
3 to 4
Moderate
  • Use sunscreen if you work outdoors and remember to protect sensitive areas like the nose and the rims of the ears. Sunscreen prevents sunburn and some of the sun's damaging effects on the immune system.
  • Use a lip balm or lip cream containing a sunscreen. Lip balms can help protect some people from getting cold sores.
5 to 6
High
  • Wear long-sleeved shirts and trousers made from tightly woven fabrics. UV rays can pass through the holes and spaces of loosely knit fabrics.
7 to 9
Very High
  • Avoid being in the sun as much as possible.
  • Wear sunglasses that block 99 to 100 percent of all UV rays (both UVA and UVB). Some reduction in blue light also might be beneficial but colors should not be severely distorted.
  • Wear a cap or hat with a wide brim, which will block roughly 50 percent of UV radiation from reaching the eyes. Wearing sunglasses as well can block the remainder of UV rays.
