Solar 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 Met Office forecasts include the effects of:
the position of the sun in the sky;
forecast cloud cover;
ozone amounts in the stratosphere.
The risk of damage to your skin can be determined, based on your
skin-type, from the table.
