UV Index Reference and Burn Time
The UV index reports the strength of the sun ultraviolet radiation on a scale that starts at zero and climbs past eleven, and it is your best guide to how quickly you can burn and how much protection you need. This reference tool takes the current UV index and your skin type on the Fitzpatrick scale and returns the World Health Organization risk category, plain protection advice, and a rough estimate of how long unprotected fair to darker skin can stay in the sun before burning. Fair, easily burning skin has far less natural protection than deeply pigmented skin, so the same UV index means very different safe times for different people. Enter the UV index, pick your skin type, and read the risk band and estimated burn time, plus the full color coded index scale for reference. Treat burn times as guidance, not a guarantee. Everything runs locally in your browser for instant, private lookups.

Frequently asked questions
What does the UV index tell me?
It rates the strength of ultraviolet radiation, where higher numbers mean faster skin damage; the tool maps your value to a risk level and protection advice.
How does skin type change the burn time?
Lighter skin types burn faster at the same UV index, so the tool shortens the estimated time to sunburn for fair skin and lengthens it for darker skin.
Is the burn time an exact limit?
No, it is an estimate; sweat, altitude, reflection off snow or water and sunscreen all change real burn time, so treat it as guidance not a hard cutoff.
