Understanding the UV Index is crucial for residents of Fairview, Canada, as it plays a significant role in protecting skin health and preventing sunburn. With UV levels fluctuating throughout the day, particularly peaking at a level of 7 from 1 PM to 3 PM, being aware of these measurements helps individuals take necessary precautions.
