In Wololele B, Indonesia, awareness of the UV Index is crucial for the well-being of its residents and visitors alike. Understanding the levels of ultraviolet radiation helps prevent sunburn and promotes long-term skin health, particularly in a region where the climate is characterized as Aw (tropical savanna), leading to intense sunlight exposure. With peak UV Index values soaring to 12 around midday, the risks associated with sun exposure can escalate quickly, making it imperative to stay informed and take protective measures. Being mindful of the UV Index can empower you to enjoy the sunny days safely while caring for your skin.
Starting the day with a gentle UV Index of 1 at 07:00, the sun gradually raises its intensity. By 08:00, it reaches 3, and as the morning unfolds, the UV Index climbs sharply to 5 by 09:00. The sun's strength peaks magnificently at 12 during the noon hour (12:00), making it crucial for outdoor enthusiasts to take precautions. As the afternoon progresses, the UV Index dips to 11 at 13:00 before declining to 8 by 14:00. The intensity further wanes to 4 at 15:00, dropping to 2 by 16:00, and returning to a gentle 1 by 17:00. Finally, by 18:00 and into the evening, the UV Index falls to 0, signaling a safe time for all as the sun sets. Remember to enjoy the bright hours while protecting your skin!
