The solar index does not exceed 8 in the UK (8 is rare; 7 may occur on exceptional days, mostly in the two weeks around the summer solstice). Indices of 9 and 10 are common in the Mediterranean area.


The UV Index can take the following values:
1-2 Low exposure. No protection required. You can safely stay outside
3-5 Moderate exposure. Seek shade during midday hours, cover up and wear sunscreen
6-7 High exposure. Seek shade during midday hours, cover up and wear sunscreen
8-10 Very high. Avoid being outside during midday hours. Shirt, sunscreen and hat are essential
