Understanding the UV Index in Kongwa, Tanzania is crucial for protecting your skin and ensuring long-term health. As a region characterized by a BSh climate, residents and visitors alike face heightened risks from ultraviolet radiation, particularly during the midday sun when UV levels peak at an intense 11 around noon. Awareness of UV levels helps prevent sunburn and broader skin health issues, allowing you to enjoy the beautiful Tanzanian sun safely. With maximum UV exposure coming during the late morning and early afternoon hours, being informed can empower you to take necessary precautions to shield yourself from harmful rays.
The UV Index today begins mildly at 1 from 07:00 to 08:00, indicating low sun exposure. However, as the day progresses, the index rises sharply, peaking at an intense 11 between 12:00 and 13:00—this level signifies very high risk for harm from unprotected sun exposure. As the afternoon continues, the UV Index gradually declines from 9 at 14:00 to 6 by 15:00, before dropping to 4 at 16:00. The sun’s intensity then wanes, returning to 1 by 17:00 and ultimately falling to 0 by 19:00. It's crucial to stay protected during the mid-day hours when the sun's rays are most potent!
