Understanding the UV Index is crucial for residents and visitors in Srandakan, Indonesia, where the sun shines brightly under a typical tropical climate. As the UV levels can peak at a staggering 11 during midday hours, being aware of these measurements is essential for preventing sunburn and protecting skin health. With the region’s Af climate, characterized by high temperatures and ample sunlight, it's imperative to stay informed about potential UV exposure risks throughout the day. By monitoring the UV Index, you can take the necessary precautions to enjoy the beautiful outdoors while safeguarding your skin.
The UV Index for the day tells an illuminating story of sun intensity. Early risers at 07:00 will find a mild UV level of 1, perfect for a leisurely morning stroll. However, as the sun climbs, things heat up, peaking at 11 by 11:00 and 12:00, indicating a high risk of harm from unprotected sun exposure. It’s the ideal time for sunscreen and protective gear! Post-lunch, the index begins to drop, tapering off to 4 by 15:00, and a much more manageable 1 by the evening hours. As twilight approaches, the UV Index decreases to 0 by 18:00, providing a safe haven for an evening out without the sun's glare. Remember to plan your outdoor activities around this UV profile to stay safe while enjoying the sunshine!
