Understanding the UV Index is crucial for residents and visitors of Khamcha-i, Thailand, as it serves as a vital indicator of the sun's strength and its potential impact on skin health. With a tropical climate categorized as Aw, Khamcha-i experiences high UV exposure, especially during peak hours when the index can soar to 15. Being aware of these levels is essential for preventing sunburn and safeguarding long-term skin health. With UV Index values ranging from moderate to extreme, knowing when to seek shade and apply sunscreen will help protect you from harmful effects while enjoying the beautiful Thai outdoors.
The UV Index presents a fascinating hourly journey throughout the day. It begins gently at 1 at 07:00, but as the sun climbs higher, the intensity peaks dramatically.

Finally, as the day winds down, the UV Index dips back to 1 by 17:00, and then fades to 0 as the sun sets at 19:00. It's a vivid reminder to embrace sun safety during the brightest parts of the day!
