Look for the UV-index at your place on a given day. Remember this index can change everyday, just as for example the maximum temperature does. You can find the UV-index in a local paper or on the internet. Go to the links section to find a site that returns the UV-index from all over the world.

Disclaimer

The formulas in the calculator are based on information provided by the WHO and other sources (see links section). Sundicator.net or any of the mentioned sources cannot be held responsible for any consequence that may result from the use of the above mentioned UV-calculator.

Use your common sense when exposing yourself to the sun and listen to your doctor’s advice when it comes to suncare and safe sun tanning time.To use the UV-calculator, you need to know your skin type. Basically a low number means a higher risk of skin damage. Consult the above table if you don’t know what skin type you have.
If you’re not sure, rather underestimate your skin type. For example, you’re not sure whether you really are a type 3, then choose type 2. And ask your doctor the next time you visit him.
