Solar UV Index
Solar UV Index Table
The UV index was developed by the World Health Organisation and has a scale of 0 – 11+ . Our weather forecasts include reports on the level of risk. In NI the UV index is 3 or above on many days from April to September and it can reach 7 or 8 in mid-summer. It is a much more accurate way of determining your risk of burning than just relying on the air temperature.
The UV index forecasts include the effects of:
- The position of the sun in the sky
- The altitude
- The time of day and time of year
- Cloud cover and other weather conditions
So, what do the numbers mean?
The risk of damage to your skin can be assessed based on your skin type from the information below:
- 1-2 Low Risk
The sun is unlikely to burn you whatever your skin type
- 3-4 Low-Medium Risk
If you have fair or sensitive skin you are at medium risk and should use adequate sun protection. Children fall into this category
- 5-6 High Risk
Everyone needs to use sun protection if they are outside – the recommended SPF is 15+. People with black skin are at low risk
- 7-10 High to Very High Risk
Everyone should cover up as well as using sunscreen regardless of their skin colour
- 10+ Very High Risk
People with white skin are at a very high risk
People with brown skin are at medium to high risk
People with black skin are at medium risk
CARE IN THE SUN
Anyone can develop skin cancer, whatever their skin colour. However, certain skin types are more at risk from the effects of UV radiation than others.
Too much ultraviolet (UV) light, either from natural sunlight or from artificial sources such as sunbeds, is the main cause of 80% of skin cancers.
Sunbeds, tanning booths and lamps give out harmful ultraviolet (UV) rays that damage your skin and can make it look wrinkled, older or leathery.
