Understanding the UV Index is crucial for residents of Kayunga, Uganda, where sunny weather is abundant year-round. Knowing the daily UV levels is essential for preventing sunburn and promoting overall skin health, allowing you to enjoy outdoor activities while protecting yourself from harmful ultraviolet radiation. With Kayunga’s tropical climate, the UV exposure can quickly escalate, particularly during midday, when the index peaks at a staggering 11. Being informed about these UV levels can significantly reduce the risks associated with sun-related skin damage and enhance your outdoor experience.
The UV Index today begins its climb gently at 1 early in the morning, peaking as the sun reaches higher into the sky. By 09:00, it registers a moderate 3, but from 10:00 onwards, the intensity escalates sharply, hitting 5 and then soaring to a remarkable 11 by noon. The peak persists through 13:00, holding steady at 11, a clear signal to take sun protection seriously. As the afternoon unfolds, the index gradually recedes, dropping to 10 at 14:00, and further declining to 7 by 15:00. The UV Index continues to diminish as the day winds down, settling at 4 by 16:00, then slipping to 2 at 17:00, and finally returning to a safe 1 by 18:00. The day ends on a low note of 0 at 19:00, providing a much-needed respite from the sun’s rays. Stay protected during those peak hours!
