What is the UV Index?

Some exposure to sunlight can be enjoyable; however, too much could be dangerous. Overexposure to the sun's ultraviolet (UV) radiation can cause immediate effects such as sunburn and long-term problems such as skin cancer and cataracts. The UV Index, which was developed by the National Weather Service and the U.S. Environmental Protection Agency (EPA), provides important information to help you plan your outdoor activities to prevent overexposure to the sun's rays.

The UV Index provides an indicator of the expected risk of overexposure to the sun. The Index measures UV intensity levels on a scale of 1 to 11+, where low indicates a minimal risk of overexposure and 11+ means an extreme risk. The UV Index takes into account clouds and other local conditions that affect the amount of UV radiation reaching the ground.

By taking a few simple precautions, you can greatly reduce your risk of sun-related illnesses. To Be SunWise, consider the following steps:

  • Limit your time in the sun between 10 a.m. and 4 p.m.
  • Whenever possible, seek shade.
  • Use a broad spectrum sunscreen with an SPF of at least 15.
  • Wear a wide-brimmed hat and if possible, tightly woven, full-length clothing.
  • Wear UV-protective sunglasses.
  • Watch the daily UV Index.

While you should always take precautions against overexposure to the sun, please take special care to adopt the safeguards when the UV Index indicates levels of moderate or above.

MONSOON
The best example of a monsoon on Earth occurs over the Indian sub continent. During the months of April through October, a moist southwest wind brings heavy rains to this region...while a dry northeast wind is prevalent during the remainder of the year.

In North America, a similar situation occurs over much of Mexico. For example, in Acapulco, rainfall averages 51.8 inches during the months of June through October...while only 3.3 inches falls during the remainder of the year.

In the United States, Arizona and New Mexico are located on the northern fringe of the Mexican Monsoon. For most of the year, winds aloft over the southwest U.S. are west to northwest. During the summer, winds turn to a more south to southeast direction, importing moisture from the Pacific Ocean, the Gulf of California and the Gulf of Mexico.
