In Chaloem Phra Kiat, Thailand, being aware of the UV Index is crucial for safeguarding your skin against harmful ultraviolet rays. Understanding UV levels is essential not only for preventing sunburns but also for maintaining long-term skin health. With a tropical climate that naturally exposes residents and visitors to high UV levels—peaking at a staggering 14 at noon—awareness of these risks becomes even more vital. As you enjoy the beautiful sunshine in this vibrant region, monitoring the UV Index can help you make informed decisions to protect yourself during the day and enjoy the outdoors safely.
As the day unfolds, the UV Index paints a vivid picture of solar intensity. Starting off gently at 1 at 07:00, the sun quickly ramps up its energy, reaching 3 by 08:00. But it’s by 10:00 that the real power emerges, peaking at a striking 10. The intensity continues to soar, hitting its apex at 12:00 with a blistering 14. As the afternoon heats up, it gradually declines, descending to 12 by 13:00, then down to 10 at 14:00. By late afternoon, the sun’s grip loosens, dropping to 6 at 15:00, before retreating to a gentle 3 by 16:00. Finally, as the sun sets, the UV Index diminishes to 1 at 17:00 and fades to 0 by 19:00, signaling the end of another bright day. Remember to protect your skin during those peak hours!
