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 Organization. These 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:
| 1-2 | 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 |
| 11 or over | Extreme. Avoid being outside during midday hours. Shirt, sunscreen and hat essential. |
