In Butiama, Tanzania, understanding the UV Index is crucial for ensuring skin health and preventing sunburn. With a climate that often exposes residents and visitors to intense sunlight, especially between the peak hours of 10 AM to 2 PM when UV levels can reach as high as 13, awareness of UV levels can empower individuals to take protective measures. Monitoring the UV Index helps you make informed decisions about sun safety, allowing you to enjoy the beautiful outdoors while significantly reducing the risk of skin damage. Being informed about these risks is essential in a place where the sun shines bright and often.
As the day unfolds, the UV Index climbs steadily, starting at a moderate 1 at 07:00 and peaking at a scorching 13 from 12:00 to 13:00. This spike signifies a heightened risk of harm from unprotected sun exposure, particularly around 11:00, when the index hits 11—a strong warning to seek shade and wear sunscreen. A gradual decline begins at 14:00, dipping to 8 by 15:00, before sliding back to a safe 2 by 17:00 and ultimately falling to 0 as daylight fades at 19:00. Plan outdoor activities wisely to minimize sun damage during those peak hours!
