Understanding the UV Index is crucial for residents and visitors of Annaba, Algeria, where the Mediterranean climate brings plenty of sunny days. With UV levels frequently peaking during midday, being aware of these levels can significantly help in sunburn prevention and overall skin health. Annaba's Csa climate typically exposes individuals to higher UV radiation, especially between 11:00 AM and 2:00 PM, when the index soars to a high of 9. By keeping a close eye on the UV Index, you can take proactive measures to protect your skin and enjoy the sun safely!
The UV Index today starts off gently at 1 by 7:00 AM, but as the sun rises, it quickly escalates. By 10:00 AM, the index reaches 6, climbing to a peak of 9 at both 12:00 PM and 1:00 PM, when the sun is at its highest and strongest. As the afternoon progresses, the numbers begin to wane; by 3:00 PM, it's down to 6, and it further drops to 2 by 5:00 PM, before settling back at 1 by evening. This data highlights the importance of sun safety, particularly between 11:00 AM and 1:00 PM when the UV levels are most intense and skin protection is essential.

During this period, particularly in June when the Index reaches a staggering 11 indicating an extreme risk, residents and visitors should exercise caution.
