In Ujung Gading, Indonesia, awareness of the UV Index is crucial for protecting your skin and overall health. With climate conditions classified under the Af (tropical rainforest) zone, residents and visitors face varying levels of ultraviolet radiation throughout the day. Understanding UV levels is essential as it helps prevent sunburns and reduces the risk of long-term skin damage. During peak hours, especially between 11:00 AM and 1:00 PM, the UV Index can soar to extreme levels of 13, underscoring the importance of taking precautions. Stay informed and safeguard your skin against the hidden dangers of the sun!
As the sun rises over the horizon, the UV Index starts low at 1 by 7:00 AM, gradually ramping up to 2 by 8:00 AM. However, by 9:00 AM, it takes a significant leap to 4, with intensity peaking at a notable 13 by 12:00 PM. The midday sun brings the highest risk, striking 11 at 11:00 AM, followed closely by 12 at 1:00 PM. The intensity begins to wane as the afternoon progresses, dipping to 10 at 2:00 PM, then gently declining to 7 by 3:00 PM. As the sun sets, the index drops to 1 by 5:00 PM, and ultimately fades away to 0 after 7:00 PM. It's a day of vibrant sunshine, and while the midday hours call for caution, the gradual descent of UV radiation offers a pleasant evening breeze.
