Understanding the UV Index is crucial for residents of Shelburne, Canada, as it provides essential information about the intensity of ultraviolet radiation throughout the day. Being aware of UV levels helps in preventing sunburn and promoting overall skin health, safeguarding against the long-term effects of sun exposure. With Shelburne's Dfb climate, characterized by warm summers, residents face heightened UV risks, especially during midday hours when readings can reach up to 10. By staying informed about the UV Index, you can enjoy the outdoors while protecting your skin from potential harm.
As the sun rises, the UV Index reflects a gradual increase in solar intensity throughout the morning. Starting at a mild 1 at 07:00, exposure levels climb steadily, reaching 2 by 08:00 and 3 at 09:00. The intensity peaks at 10 between 13:00 and 14:00, marking the most dangerous hours for sun exposure. A slight decline occurs as the afternoon rolls into evening, with readings dropping to 8 at 15:00, then 4 at 17:00, and finally waning back to 1 by 19:00. It’s clear: if you're planning to soak up the sun, protect yourself during those peak hours!
