In Hacienda Santa Rosa, Philippines, understanding the UV Index is crucial for safeguarding your skin and overall health. With intense sunlight typical of its tropical climate, awareness of UV levels can help prevent sunburn and reduce long-term skin damage. As UV readings soar during midday—peaking at a striking 14 at noon—it’s vital to stay informed and take protective measures. By monitoring the UV Index, residents and visitors can enjoy the sun while minimizing the risks associated with excessive exposure.
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!
