The UV-index is an international standard measurement of the strength of erythemogenic ultraviolet radiation. It is often published in the media and then refers to the highest expected UV radiation for that day. The highest UV-index value measured in Iceland is seven. Although this is similar to the maximum values from southern Scandinavia, the average UV-index is lower in Iceland compared to other Nordic countries. Around solar noon the UV index is roughly equivalent to the Standard Erythema Dose (SED). During a bright summer day in Iceland the number of Standard Erythema doses can go as high as 32, but is on average in June around twenty. The typical Icelander gets red after 4-6 SED and it is obvious that during solar noon it is easy to sunburn in Iceland if you stay outside without sun protection.
