Understanding the UV Index is crucial for residents of Tinongan, Philippines, where the tropical climate often leads to high levels of ultraviolet (UV) exposure, especially during midday hours. Awareness of UV levels can significantly enhance sunburn prevention and promote long-term skin health, as the risk of skin damage increases dramatically when UV Index values soar to 14 during peak hours. With a climate characterized by ample sunshine, knowing when to seek shade and how to protect your skin is vital for enjoying the outdoor activities that Tinongan has to offer, without compromising your health.
As the sun rises, the UV Index gradually climbs, starting with a mild 2 at 07:00. By 08:00, it reaches 4, signaling a need for some sun protection. However, as the day progresses, the index spikes to its peak at 12:00, hitting an intense 14. This mid-day period, particularly from 10:00 to 13:00, is critical, with readings of 10 and 13 respectively, indicating a strong risk of harm from unprotected sun exposure. After the zenith of the afternoon, the index begins its descent, dropping to 9 by 14:00, and further down to 5 by 15:00. As the sun sets, the UV intensity diminishes rapidly, falling back to 1 at 17:00 and finally to 0 by 19:00. Throughout the day, it’s vital to stay informed and safeguard your skin during those peak hours!
