Understanding the UV Index in Ntoroko, Uganda, is vital for safeguarding your skin and overall health. The levels of ultraviolet radiation can vary dramatically throughout the day, making it essential to be aware of UV levels, especially during peak hours. High UV exposure, particularly between 11 AM and 2 PM, can lead to sunburn and increase the risk of skin cancer. Given Ntoroko’s tropical climate, residents and visitors are often subjected to intense sunlight, underscoring the need for proactive sun safety measures. Being informed about the UV Index not only helps in preventing skin damage but also promotes healthier outdoor activities amidst the beauty of this vibrant region.
At 07:00, the UV Index begins to rise slowly with a value of 1, remaining steady until 09:00. As the sun climbs higher, the intensity peaks sharply at 11:00 with a UV Index of 8. The zenith occurs at 12:00, reaching an impressive 11, and shortly after, it hits a maximum of 12 at 13:00. From this point, the numbers gradually decrease, as the UV Index drops to 11 at 14:00 and then to 8 by 15:00. As afternoon transitions to evening, the index further declines to 2 at 17:00, finally tapering off to a 1 by 18:00 and closing the day at a minimal 0 by 19:00. This pattern emphasizes the importance of sun safety during the peak hours from 10:00 to 14:00 when UV radiation is at its strongest.

While the index slightly decreases during the summer months of June and July to 12, the high-risk designation remains due to the persistent threat of UV radiation. Even in the fall and winter months, the UV Index does not drop below 12, maintaining an extreme exposure category.
