Understanding the UV Index is crucial for residents and visitors in Sawangan, Indonesia, where the tropical climate can lead to elevated sun exposure throughout the day. With UV levels peaking at a significant 10 around midday, awareness is key to preventing sunburn and protecting skin health. Recognizing when the sun’s rays are most intense helps you take necessary precautions, whether you're enjoying outdoor activities at the beach or strolling through local markets.
