Understanding the UV Index is crucial for residents of Saguenay, Canada, as it serves as a key indicator of daily sun exposure risk. With the potential to cause sunburns and long-term skin health issues, being aware of UV levels can help you take necessary precautions when enjoying outdoor activities. Saguenay, situated in a humid continental climate (Dfb), often experiences varying UV exposure, peaking during midday hours when levels can reach as high as 8.
