Understanding the UV Index is crucial for residents and visitors in Pangani, Tanzania, where the tropical climate brings intense sunlight year-round. With UV levels frequently peaking at 10 during midday, awareness of these measurements is essential for preventing sunburn and maintaining long-term skin health. Knowing when to seek shade or apply sunscreen can make a significant difference in reducing risks associated with high UV exposure. In this coastal gem, where the sun shines brightly, staying informed about UV levels is not just a matter of comfort—it's vital for safeguarding your well-being as you enjoy the beautiful beaches and vibrant culture of Pangani.
The UV Index throughout the day showcases a dynamic curve, peaking impressively between 12:00 PM and 1:00 PM with a remarkable score of 10, indicating a high risk of harm from unprotected sun exposure. As the sun rises, the index starts low at 1 by 07:00 AM, gradually increasing to 2 by 08:00 AM, before climbing more steeply to reach 6 by 10:00 AM. The intensity continues to rise until its zenith, with values of 9 at 11:00 AM and the maximum of 10 at noon. After this peak, the UV Index begins its descent, dropping to 8 by 2:00 PM, then gradually tapering off to 5 by 3:00 PM and further to 1 by late afternoon, ultimately falling to 0 by 7:00 PM. It's a reminder to stay protected during those peak hours!
