Sun Safety

Remember sun safety when traveling to warmer climates this year.  The same factors that we consider in the summer affect the amount of ultraviolet (UV) radiation exposure you will encounter in any season.

The amount of exposure you get from ultraviolet (UV) radiation depends on several factors:

  • Time of day:  Maximum exposure to UV radiation occurs between 10 am and 4 pm.

  • Season:  Intensity of UV radiation is much greater during the summer months.

  • Altitude:  UV radiation increases by 4% per 1000 feet elevation.  For example, there is 20% more UV radiation at 5000 feet (most ski resorts) than at sea level.

  • Cloud Cover:  A thin cloud cover reduces UV radiation by only 20-40%.

  • Reflection:  Reflected UV radiation is just as damaging as direct UV radiation.

          Sand/concrete reflects 25% of UV radiation

          Water reflects up to 100% of UV radiation

          Snow reflects 85% of UV radiation


Keep sun safety in mind all year round.  Snow reflects sun just like water does and you can get quite a raw burn form the combination of wind and sun.  Remember to wear sunscreen for all outdoor activities.
