Are you playing it safe in the sun? The standardized UV index scale tells you how quickly your skin will burn without protection. Check out the UV Index and the latest UV forecast for your area!
What Is the UV Index?
The ultraviolet (UV) index is a scale that represents the intensity of UV radiation produced by the sun. The index was originally created by Canadian scientists in the early 1990s and has since been adapted for use throughout the world. The UV Index also recommends “Actions to Take”—such as wearing sunscreen and a hat—to avoid getting burned.
The U.S. National Weather Service (NWS) and the Environmental Protection Agency (EPA) measure ultraviolet levels on a daily basis, and use these numbers to create daily exposure forecasts. See the UV Index forecast for your area by entering your zip code below (the information will open in a new tab) or visiting the EPA website.

UV Index Scale
Each UV Index Number is associated with “Exposure Level,” “Time to Burn,” and “Actions to Take.” People with lighter skin need to be more cautious. People with darker skin may be able to tolerate more exposure. Note that reflections off of snow, water, and white sand can nearly double UV strength.

The Shadow Rule
Follow the EPA’s Shadow Rule to estimate how much UV radiation you are being exposed to:
- If your shadow is longer than you are tall, UV exposure is lower.
- If your shadow is shorter than you are tall, UV exposure is higher and you should take necessary precautions.
