Autumn activities like football season and school might be upon us, but summer-like weather continues for many this weekend.
During summer the UV index can reach its highest levels beneath unbroken sunshine. Even on a cloudy day, UV levels can still be high with UV able to be reflected and scattered in the clouds.
There are three types of UV rays: UVA, UVB, and UVC. UVC is the most dangerous form of UV radiation, but luckily this is absorbed by the atmosphere before it reaches Earth.
UVB penetrates the top layer of the skin and leads to sunburn. UVA is the most potent source which we are exposed to all year long. It can pass through windows and clouds and penetrates deep into our skin, leading to ageing and increasing our risk of skin cancer.
Because of the dangers associated with increased levels of UV, particularly in the spring and summer months when UV radiation is at its strongest, the UV Index was created. The higher the UV Index, the stronger the UV radiation and faster the skin will burn.
Although it is September, the angle of the sun's rays are still high in the sky. The UV index can exceed 6 or 7 on the scale.
At this level, there is a risk of burning within 30 to 60 minutes. As we spend more time outside, be sure to check the UV Index level near you inside our app!
With plenty of clear skies ahead, your skin can still burn. Check the WeatherRadar for the latest sky conditions..
