Using sunscreen does not mean it is safe to spend more time in the sun, especially when the UV Index is high. Although a sunscreen with an SPF of 15 or higher offers protection from sunburn, it does not block all of the sun's damaging rays. To fully protect yourself, remember to seek shade, minimize peak hours of sun exposure, and wear protective clothing in addition to applying sunscreen.

The intensity of the sun's UV rays reaching the Earth's surface varies and should be considered when you plan outdoor activities. The National Weather Service issues the UV Index, a daily forecast of UV intensity, for the United States.

The higher the UV Index forecast, the stronger the sun will be and the greater the need to follow all the sun protection action steps. For days when the UV Index is unseasonably high for a particular location, EPA issues a UV Alert.

In general, UV strength is greatest from 10 a.m. to 4 p.m. during sunny summer days. Up to 80 percent of UV rays pass through clouds, however, meaning that sunburn is possible on cloudy days as well. UV exposure is greater at low latitudes (nearer to the equator) and/or high altitudes. Snow, water, and sand also increase sun exposure by reflecting incoming UV rays, making it especially important for skiers, boaters, and beachcombers to wear clothing and hats and apply sunscreen.
