In the lead up to Skin Cancer Action Week Nov 15-21 – see the following information:

What is UV?
Ultraviolet (UV) radiation is a type of energy produced by the sun and some artificial sources, such as solariums.
The sun’s ultraviolet (UV) radiation is the main cause of skin cancer. UV damage also causes sunburn, tanning, premature ageing and eye damage.
UV radiation isn’t like the sun’s light or heat, which we can see and feel. Your senses cannot detect UV radiation, so you won’t notice the damage until it has been done.

The UV Index
The World Health Organization's Global Solar UV Index measures UV levels on a scale from 0 (Low) to 11+ (Extreme).
Sun protection is recommended when UV levels are 3 (Moderate) or higher.

Sun protection times
The sun protection times show when UV levels are forecast to be 3 or higher.
You can find the sun protection times for your location on the free SunSmart app.
Click on the SunSmart widget  to see today’s UV levels are  in your local area or visit the Bureau of Meteorology website .

ALWAYS:  During the sun protection times remember to protect your skin and eyes by using covering clothing, sunscreen, a hat, shade and sunglasses. Don’t just wait for hot and sunny weather
