EPA's SunWise UV Index

By United States Environmental Protection Agency (USEPA)

This app is only available on the App Store for iOS devices.


The UV Index provides a daily and hourly 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!

Customer Reviews

It's good, however....

This is a good UV index app however there certain days where I just cannot access the hourly and daily uv index using my current location. I keep trying to delete and download the app but just doesn't want to work at times once in a while. Today is one of those days where it just doesn't want to work. Please find a way to fix these bugs or I will no longer use

please update this app !!

would be 10 stars for sure if i didn't keep getting "forbidden access" error messages every time i click anywhere on the screen -- it works 10% of the time -- but when it does .. IT IS AMAZING ! this app has the potential to negate having any other UV Index apps ... PLEASE UPDATE for bug fixes !!!

Few Issues, Overall Great App

Everything seems to work fine except the hourly forecast. This feature worked for only one day, the day I downloaded the app. I would appreciate if you would please fix this bug.
