The UV index is a number linearly related to the intensity of sunburn-producing UV radiation at a given point on the earth's surface. It cannot be simply related to the irradiance (measured in W/m 2) because the UV of greatest concern occupies a spectrum of wavelength from 295 to 325 nm, and shorter wavelengths have already been absorbed a great deal when they arrive at the earth's surface.

It has been designed to indicate the potential for adverse health effects and to encourage people to protect themselves. The higher the Index value, the greater the potential for damage to the skin and eye, and the less time it takes for harm to occur. UV-indekset er et udtryk for intensiteten af Solens ultraviolette stråling og dermed, hvornår du skal passe på i Solen. Husk, du kan også blive solskoldet, selv om det er overskyet. Du finder dagens UV-indeks i vejrudsigten for netop din lokation ved at folde dagene i oversigten ud. UV-index är högst under middagstid då solen står högst på himlen, och när det är molnfritt. Genom att kolla indexet kan du få svar på när du bör se upp med solen och använda solskydd.
