Understanding the UV Index in Kirando, Tanzania, is essential for safeguarding your skin and overall health. With the region's Aw climate, residents and visitors experience consistent exposure to ultraviolet radiation, particularly during the peak hours when the UV Index can reach a high of 11. Being aware of daily UV levels is crucial, as it helps prevent sunburn and reduces the risk of long-term skin damage. With such intense sunlight, knowledge of UV exposure can empower you to take necessary precautions, ensuring you enjoy the beautiful outdoors without compromising your skin's health.
The UV Index today presents a dynamic journey from dawn to dusk. Starting off with a 0 at 07:00, early risers are safe from harmful rays. As the sun climbs higher, the index ticks up to 1 by 08:00 and then to 2 at 09:00, signaling the gentle start of UV exposure. 10:00 marks a noticeable increase, soaring to 5, but the peak arrives at 12:00 with an impressive 10—a point where sunscreen becomes a must! The intensity of UV radiation continues to rise, hitting 11 at 13:00, before gradually declining to 7 by 15:00. As the day winds down, the UV Index declines to 4 at 16:00, dipping further to 2 by 17:00, and finally retreating to a safe 0 as evening approaches at 19:00. Plan outdoor activities wisely to stay protected during those peak hours!
