Ultraviolet radiation (UV) is a component of sunlight. The Global Solar UV index is a scale that was developed by the World Health Organisation which measures the UV radiation level at the surface of the Earth, and gives an indication of the potential for skin damage. The graph shows the current UV Index level as measured at Valentia Observatory Co.Kerry. The UV Index level for your location is included in each of our Regional Weather Forecasts during summer months. Further information below.

- The UV index for Ireland is included in forecasts from May to September but be aware it can only be an average for any one day over the entire country. The clear/sunny sky peak UVI index is reduced by cloud cover.
- For example when the sky is cloud free (sunny) everywhere in Ireland then the UVI for Ireland is high (7.5) in June/July between 11am and 4pm. If it is cloudy everywhere then the UVI is low to moderate (3 to 4).
- Often however the cloud is variable from place to place and from time to time in Ireland and due to wind chill it can often feel cool in summer. Nonetheless a 20 minutes sunny interval can produce sunburn.
