In Kosti, Sudan, understanding the UV Index is essential for safeguarding your skin and overall health. With the city's BWh climate, residents and visitors are exposed to significant UV radiation, particularly during the midday hours when levels can soar to 11—a critical threshold where sunburn can occur in just minutes. Being aware of these levels is vital for effective sunburn prevention and long-term skin health. As you navigate daily life in Kosti, staying informed about UV exposure can help you protect yourself and enjoy the vibrant sunshine safely.
Starting off the day at a moderate UV Index of 2 at 07:00, the sun quickly rises in intensity, reaching a peak of 11 by midday at 12:00. This powerful UV exposure indicates a need for sun protection, especially from 11:00 to 13:00. As the afternoon unfolds, the index begins to dip, dropping to 9 by 13:00 and then gradually decreasing to 4 at 15:00. By evening, the risk subsides significantly, with the UV Index falling to 1 by 17:00 and finally hitting 0 after 19:00. Whether you're planning outdoor activities or just enjoying the day, be sure to stay protected during those high-risk hours!
