What does UV mean?
Ultraviolet (UV) radiation is radiation that is emitted by the sun. It is divided into three sub-sections:
The earth’s atmosphere blocks all UVC radiation and all but a small amount of UVB, so the ultraviolet radiation at the earth’s surface is mostly UVA and UVB. UVB is the most harmful
What is the SunSmart UV Alert?
The alert identifies the times during the day that the UV index will reach 3 or above, so people know when to adopt sun protection measures.
How is the UV forecast developed?
The UV Index forecast provides the information for the SunSmart UV Alert for cities and towns across Australia. The UV rating system used by the Bureau of Meteorology has been adapted from the World Health Organisation Global Solar UV Index.
Why are there different forecasts for different parts of Australia?
Also, because the northern states of Australia are closer to the equator they have a higher UV Index then the southern states. It is important for Australians to understand that the UV Index can change each day due to cloud cover, and is different each month and each season.
Australians should get into the habit of checking the UV Index regularly to see when they need to adopt effective sun protection
