The UV index does not exceed 8 in the UK (8 is rare; 7 may occur on exceptional days, mostly in the two weeks towards the end of June). Indices of 9 and 10 are common in the Mediterranean area. ○

In the UK, the sun's UV rays are the strongest when the sun is highest in the sky between 11am and 3pm, from [mid March] to late September. During this time, the sun can be strong enough to cause sunburn. ○
