Understanding the UV Index is crucial for residents of Labrieville, Canada, as it serves as a guiding tool for sun safety and skin health. Being aware of UV levels helps prevent sunburn and reduces the risk of long-term skin damage. Given Labrieville’s Dfc climate—characterized by cool summers—the intensity of UV radiation can be deceptively high, especially during peak hours from 11 AM to 1 PM, where the UV Index peaks at 8. By staying informed about the daily UV Index, you can enjoy outdoor activities while taking necessary precautions to protect your skin.
Starting early in the morning, the UV Index begins at a mild 1 at 07:00, gradually rising through the hours. By 09:00, it reaches 4, marking the onset of stronger sunlight. The intensity peaks between 11:00 and 13:00, with a robust 8, indicating a high risk of harm from unprotected sun exposure. From there, it starts to gradually decline, dipping to 6 by 15:00 and falling further to 4 at 16:00. As the sun begins to set, the index decreases significantly, dropping back to 1 by 18:00 and maintaining that lower level until evening. This day’s UV trends serve as a reminder to protect your skin during peak hours, especially when the index is at its highest.
