Understanding the UV Index is essential for residents of Qikeshu, China, where the climate's Dwb zone brings varied exposure to harmful ultraviolet rays throughout the day. Being aware of UV levels helps in preventing sunburn and safeguarding skin health, especially during peak hours when the index reaches a maximum of 9 around noon. With UV intensity climbing as early as 8:00 AM, reaching critical levels by 11:00 AM, it's crucial to take proactive measures against UV exposure. Staying informed about these fluctuations not only promotes better skin care but also enhances outdoor activities while minimizing risk.
As the sun rises, the UV Index begins to climb, starting at a gentle 2 at 07:00. By 08:00, it reaches a moderate 4, and as the day progresses, the intensity continues to increase. At 09:00, it spikes to 6, and by 10:00, we see a peak of 7. The sun’s strength culminates at 11:00 with a high of 8, before reaching its zenith at 12:00 with an impressive 9. As the afternoon unfolds, the indices retract; 1:00 PM sees a slight drop to 8, and by 2:00 PM, it settles back to 7. In the later hours, the intensity decreases further, with 5 at 3:00 PM, then 3 by 4:00 PM, and fades to 2 at 5:00 PM. Finally, as the sun sets, the UV Index dwindles to 1 by 6:00 PM and remains steady through 7:00 PM. It’s a reminder to enjoy the sunshine wisely, especially during the midday peak!
