Understanding the UV Index is essential for residents of Bojonggaling, Indonesia, where the tropical climate often brings high levels of ultraviolet radiation. Being aware of UV exposure not only helps in preventing sunburn but also plays a significant role in maintaining long-term skin health. Throughout the day, especially between 10 AM and 2 PM, the UV index can soar, reaching a maximum of 11—a level that indicates a very high risk of harm from unprotected sun exposure. With typical UV risks combined with the region's sunny climate, staying informed can protect you from harmful effects while enjoying the beautiful outdoors.
The UV Index paints a vivid picture of the sun's intensity throughout the day. At 7:00 AM, it's a gentle 1, gradually rising to a moderate 2 by 8:00 AM. As the morning progresses, the index makes a substantial jump to 5 at 9:00 AM, peaking at an intense 11 from 11:00 AM to 12:00 PM—a time when sun protection becomes essential. The heat starts to taper slightly by 1:00 PM with a reading of 10, falling to 7 by 2:00 PM. By late afternoon, the coverage dwindles, dropping to 4 at 3:00 PM and lingering at 2 by 4:00 PM. As the day winds down, the index dwindles further to 1 at 5:00 PM and finally fades to 0 by 6:00 PM. Protect your skin when the sun is strong, especially during those peak hours!
