Understanding the UV Index is crucial for residents and visitors of Denggen Daya, Indonesia, as it serves as a vital tool for protecting skin health and preventing sunburn. Given the region's tropical climate, which typically subjects individuals to high levels of UV exposure, awareness of daily UV levels helps people make informed decisions about sun safety. For instance, during peak hours around noon, the UV Index spikes to 11, indicating an extreme risk of harm from unprotected sun exposure. By staying informed and taking appropriate precautions, you can enjoy the beauty of Denggen Daya while safeguarding your skin against the potentially harmful effects of UV radiation.
The UV Index reveals a dynamic pattern throughout the day, peaking during the midday hours. At 07:00, the index starts low at 1, gradually rising to 2 by 08:00. Things heat up significantly by 10:00, soaring to 7, and reaching its maximum of 11 at 12:00 and 13:00—the perfect time for sun protection. As the afternoon sets in, the index gracefully declines, dropping to 8 at 14:00, then tapering off to 5 by 15:00, and further down to 3 at 16:00. By the time evening arrives, the UV Index returns to a safe 1 at 17:00 and further diminishes to 0 by 19:00.
