Understanding the UV Index is crucial for residents and visitors in Ketapang, Indonesia, where the tropical climate brings a consistent risk of harmful ultraviolet radiation. With UV levels peaking during midday hours, being aware of these fluctuations is key to preventing sunburn and maintaining long-term skin health. In a region characterized by its warm temperatures and bright sunshine, knowing when to seek shade or apply sunscreen can make all the difference. As the UV Index rapidly climbs to high levels, especially between 10 AM and 1 PM, it's essential to stay informed and protect your skin from potential damage.
At sunrise, the UV Index starts at a mild 1 at 7:00 AM, offering a gentle welcome to the day. As the sun climbs higher, the intensity increases, reaching a moderate 3 by 8:00 AM. By 9:00 AM, it escalates to a strong 6, signaling the need for sun protection. The peak arrives at 11:00 AM and 12:00 PM, where the UV Index hits a staggering 12, indicating extreme levels of UV radiation. As the afternoon progresses, the intensity gradually declines, dropping to 8 at 2:00 PM and continuing to diminish through the late afternoon—4 at 3:00 PM, 2 at 4:00 PM, and finally returning to a safe 1 by 5:00 PM. The day winds down with no UV concern after 6:00 PM as the index falls to 0, allowing for a worry-free evening under the twilight sky.
