UV Index Resources

SunWise provides a variety of applications and resources that provide the UV Index forecast and help you stay safe in the sun. Learn more about the UV Index.

How can I display UV Index information on my site?

The SunWise Program has developed an XML code that allows a Web developer versed in XML (Extensible Markup Language) to display UV Index and Alert forecasts on any Web site. The information is searchable by ZIP Code and city, state, making it useful for any organization, either local or national. Users do not have to leave your site to see the forecast.

What does e-mail have to do with skin cancer prevention?

Subscribe to receive emails with the UV Index forecast for your ZIP code or city, state. The forecast and accompanying recommendations for sun protection will help you plan a sun-safe day and prevent overexposure to UV radiation. You many customize the UV Index level for which you would like to receive notifications. You may also subscribe to receive emails only on days when there is a UV Alert for your area.

E-mails go out in the early evening, so you have plenty of time to prepare for your next day’s activities. If you planned on a picnic, and the UV Index is predicted to be a 10 for your ZIP code, you’ll know that you will need to be extra careful to minimize sun damage to your skin and eyes.
It’s easy to subscribe and unsubscribe, so if you’ll be traveling for a few days, and you have access to your e-mail, you can receive the local UV Index wherever you are traveling.
