Some interesting and useful facts to know about how UV radiation levels differ.
The higher the sun is in the sky, the greater the level of UV radiation. This is why the levels vary throughout the day and the time of the year. The levels tend to be highest when the sun it at its highest, around midday (noon) during the summer months.
UV radiation penetrates through cloud cover so even if it's cloudy, remember to protect your skin.
The closer you are to the equatorial regions, the higher the UV radiation levels.
At higher altitude, the atmosphere is thinner and absorbs less UV radiation. As a barometer, with every 1000 meters increase in altitude, UV radiation levels increase by 10 to 12%.
The ozone layer absorbs some of the UV radiation but it is not the same thickness around the planet. Some areas like Australia and New Zealand are thinner than in other regions, which means that these countries are less protected. Also, ozone levels vary over the year and even throughout the day!
REFLECTION FROM THE GROUND
UV radiation is reflected or scattered depending on the surface. Gresh snow can reflect as much as 80%, dry beach sand about 15% and sea water about 25%.

Getting to know your skin is probably the single most important thing you can do to help detect skin cancer symptoms. Check your moles regularly and keep a record of things popping up or growing on your skin.
If you notice any signs consistent with the list highlighted below that concern you or persist for two weeks, visit your doctor. There's a good chance that it's nothing - but why put it off? Early detection saves lives.
Modern sun protective clothing is produced from fabrics which are rated for their level of ultraviolet (UV) protection. This gives the fabrics their ultraviolet protection factor (UPF) rating.
A UPF is the rating used for Fabrics, whereas a SPF is the rating used for Sunscreen.
A rating of UPF50+ is the highest rating achievable on the market and blocks more than 98% of UV rays. All Solbari products are tested and rated UPF50+ in Australia.
Regular clothing such as a white cotton t-shirt or hat may only have a UPF of 5, equivalent to wearing SPF5 sunscreen.
Myth number 1: Sunscreen is all I need
The use of sunscreen is just one of a number of skin protection measures you should use every day. According to dermatologists, it should not be your primary form of protection and not your only one.
- Wear UPF50+ sun protective clothing that block UVA and UVB rays
- Wear a broad brim sun hat with a UPF50+ rating.
- Wear sunscreen with a SPF of 50+ on areas not covered by your UPF50+ clothing. Apply it 20 minutes before going out, and reapply every 2 hours....
