In Rosso, Mauritania, being aware of the UV Index is vital for safeguarding your skin and overall health. Understanding UV levels helps you prevent sunburn and reduce the risk of skin-related illnesses, especially in a climate characterized by hot, dry conditions typical of the BWh climate zone. During peak sunlight hours, particularly between 11 AM and 1 PM, the UV Index can reach extreme levels, with readings soaring up to 13. This knowledge equips residents and visitors alike to implement essential sun protection measures and enjoy the sunny days safely.
The UV Index for the day tells a fascinating story of rising intensity under the sun. Early risers at 07:00 and 08:00 experienced a mild UV Index of 1, perfect for leisurely outdoor activities. As the day progressed, the index climbed steadily, reaching a moderate 3 by 09:00. By 11:00, it surged to 9, marking the start of peak sun exposure. The sun blazed at 12:00, reaching a high of 12, and continued to shine at 13:00 with an impressive 13. Throughout the afternoon, the intensity began to retreat, falling to 12 by 14:00 and gently tapering to 9 at 15:00. By evening, the sun’s grip loosened, with the index dropping to 3 at 17:00 and finally returning to a gentle 1 by 18:00 and 19:00. A day filled with sunshine serves as a reminder to stay protected during those peak hours!
