In Werda, Botswana, understanding the UV Index is crucial for protecting your skin and overall health. As residents enjoy the warm BWh climate, it is essential to stay informed about UV levels throughout the day to prevent sunburn and long-term skin damage. With peak UV Index values reaching up to 6 around midday, awareness becomes vital as exposure risks rise significantly, especially when engaging in outdoor activities.
