Understanding the UV Index is crucial for residents and visitors in Siaton, Philippines, where the sun shines brightly in a tropical climate. With UV levels peaking as high as 14 during midday, awareness of these fluctuating rates is essential to safeguard against sunburns and long-term skin health issues. The risks associated with prolonged sun exposure are heightened in this coastal town, making it imperative to stay informed about daily UV readings. Whether you're lounging on the beach or exploring the outdoors, understanding the UV Index can help you enjoy the sun safely and protect your skin.
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!
