In Krajan Bandilan, Indonesia, understanding the UV Index is crucial for safeguarding your skin health against harmful sun exposure. The UV Index provides essential information about the strength of ultraviolet radiation, helping residents and visitors alike prevent sunburn and minimize the risk of long-term skin damage. Given the region's Aw climate, characterized by significant sun exposure, the UV levels can peak dramatically, reaching a maximum of 11 around midday. By staying informed about these UV levels, you can enjoy the beautiful Indonesian sun while effectively protecting your skin from its adverse effects.
As the sun rises, the UV Index begins to climb, peaking dramatically at 11 by 11:00 AM, signaling the day's intense sun exposure. From a gentle 2 at 7:00 AM, the index escalates through the morning, hitting 9 by 10:00 AM and reaching a midday pinnacle of 11. After this height, the UV levels start their gradual descent, dropping to 8 by 1:00 PM and further tapering off to 5 at 2:00 PM. As afternoon turns to evening, the UV Index decreases significantly, settling at 0 by 7:00 PM. This data highlights the importance of sun protection during the peak hours, especially between 10:00 AM and 2:00 PM, when the potential for skin damage is at its highest. Stay safe and enjoy the sunshine wisely!
