Understanding the UV Index is crucial for residents of Sungairaya, Indonesia, where the tropical climate brings intense sun exposure year-round. Being aware of UV levels can significantly aid in preventing sunburn and preserving skin health, as harmful rays peak dramatically in the midday hours. With UV Index readings soaring as high as 14 around noon, it’s vital to take protective measures during these hours. In Sungairaya's Af climate, where sunshine is abundant, knowing when to seek shade and wear sunscreen can make all the difference in enjoying the great outdoors safely.
The UV Index throughout the day follows a striking pattern, peaking sharply during the midday hours. Starting early, at 07:00, it begins at a modest 1, slowly climbing to 2 by 08:00. As the sun rises higher, the index reaches a significant 9 by 10:00 and escalates to a glaring 14 at 12:00, marking the height of solar intensity. Interestingly, this midday zenith of 12:00 draws a slight decline by 14:00, settling at 10. From there, a gentle descent occurs, with values dropping to 6 by 15:00 and further down to 3 at 16:00. The evening hours see a return to low levels, closing out the day with 1 at 17:00 and fading to 0 by 19:00. This data highlights the critical need for sun protection during the peak hours when UV radiation is the strongest.
