UV Index
The strength of the sun's ultraviolet (UV) radiation is expressed as a 'Solar UV Index', a system developed by the World Health Organisation.
These Met Office forecasts include the effects of:
  • the position of the sun in the sky
  • forecast cloud cover
  • ozone amounts in the stratosphere
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 to 2 Low exposure. No protection required. You can safely stay outside
3 to 5 Moderate exposure. Seek shade during midday hours, cover up and wear sunscreen
6 to 7 High exposure. Seek shade during midday hours, cover up and wear sunscreen
8 to 10 Very high. Avoid being outside during midday hours. Shirt, sunscreen and hat are essential
11 or over Extreme. Avoid being outside during midday hours. Shirt, sunscreen and hat essential.
