In Baie aux Huitres, Mauritius, being aware of the UV Index is crucial for both sun safety and skin health. The UV Index provides vital information about the intensity of sun exposure throughout the day, helping you take precautions against sunburn and long-term skin damage. With a tropical climate typical of Baie aux Huitres, UV levels can peak sharply, especially between 10 AM and 1 PM, when they can reach as high as 8—indicating a significant risk for unprotected skin.
