Understanding the UV Index in Ko Chan, Thailand, is crucial for both residents and visitors alike. Awareness of UV levels plays a pivotal role in protecting against sunburn and promoting long-term skin health, especially given the tropical climate that exposes individuals to higher UV radiation levels. With peak UV Index readings reaching as high as 13 from noon to early afternoon, the risk of harmful effects on skin increases significantly. As you enjoy the beautiful sun-drenched days in Ko Chan, staying informed about UV exposure helps ensure a safe and enjoyable experience while protecting your skin from potential damage.
As the sun rises, the UV Index begins its ascent, starting at a gentle 1 at 7:00 AM. By 8:00 AM, it jumps to 3, a signal to enjoy some morning sun responsibly. The real intensity kicks in at 9:00 AM, peaking at 12:00 PM with a blistering 13—a reminder to seek shade and slather on that sunscreen! After the midday heat, the index begins to decline, dipping to 10 at 2:00 PM, and down to 1 by 5:00 PM. Finally, the day winds down at 6:00 PM with a UV index of 1, wrapping up the daylight hours with minimal UV exposure. Stay sun-safe and keep that SPF handy during those peak hours!
