UV Index Chart: Time to Burn

Prevent Sunburns with These Tips

Beach Imbrella

The UV Index chart tells you how quickly you will burn your skin without protection so that you can apply sunscreen as often as needed.

The U.S. National Weather Service measures ultraviolet levels on a daily basis, and uses these numbers for various exposure levels.

“Time to Burn” and “Actions to Take” apply to people with fair skin that sometimes tans but usually burns. People with lighter skin need to be more cautious. People with darker skin may be able to tolerate more exposure.
