Understanding the UV Index is crucial for everyone living in or visiting Maramba, Tanzania. With the region's Am climate, basking in the warm sun can quickly lead to increased risk of sunburn and long-term skin health issues if precautions aren't taken. During peak hours, particularly from 10:00 AM to 1:00 PM, the UV Index can soar to levels as high as 11, indicating a very high risk of harm from unprotected sun exposure. By being aware of the UV levels throughout the day, residents and visitors can effectively shield themselves, enjoying the outdoors safely while protecting their skin.
The UV Index for the day presents a clear picture of sun intensity, starting off gentle in the early hours. At 7:00 AM, it begins at a mild 1, increasing to 2 by 8:00 AM. As the sun rises higher, the index climbs rapidly; by 10:00 AM, it reaches 7 and peaks at an intense 11 around 12:00 PM and 1:00 PM. After this zenith, the levels gradually decline, dropping to 9 by 2:00 PM, 6 at 3:00 PM, and settling back to a safe 1 by 5:00 PM. The UV exposure diminishes further, reaching a low of 0 by 7:00 PM. Stay protected during those peak hours!
