In Menggala, Indonesia, a deeper awareness of the UV Index is crucial for protecting your skin and overall health. With its tropical climate and high sun exposure, understanding UV levels can help prevent sunburn and long-term skin damage. During the peak daylight hours, particularly between 10 AM and 1 PM, UV Index readings can soar to a maximum of 11, indicating extreme risk. By staying informed and taking necessary precautions, residents and visitors can fully enjoy the sunny days while safeguarding against harmful rays.
The UV Index today shows a striking progression through the hours. Starting the day with a mild 1 at 07:00, it quickly ramps up to 3 by 08:00, indicating that sun exposure is starting to become relevant. By 09:00, it reaches 5, marking the beginning of a more intense sun experience. The 10:00 hour brings a sharp increase to 8, while 11:00 and 12:00 peak at an impressive 11—signifying a very high risk of harm from unprotected sun exposure. As the afternoon continues, the index gradually dips, dropping to 10 at 13:00, then sliding to 8 by 14:00, before decreasing further to 4 at 15:00. The sun’s intensity wanes into the evening, falling to 2 at 16:00, and finally reaching 1 by 17:00. By 18:00 and beyond, the UV Index falls to 0, offering a reprieve from the sun’s rays as the day concludes. Always remember to stay protected during those peak hours!
