Understanding the UV Index is crucial for residents and visitors of Yongquan, China, where the subtropical climate (Cfa) brings intense sun exposure, especially during summer months. Being aware of UV levels helps in preventing sunburns and safeguarding your skin health, as UV rays can lead to long-term damage. With peak UV Index readings soaring to 12 around midday, it’s essential to take precautions against potential risks, such as skin cancer and premature aging. By keeping an eye on the UV Index, you can enjoy the beautiful sunny days in Yongquan while protecting your skin from harmful effects.
The UV Index provides a vital insight into sun exposure throughout the day, peaking during the late morning to early afternoon hours.

The real surge happens between 09:00 and 12:00, where it climbs dramatically to a maximum of 12 at 11:00 and 12:00. As the sun begins to dip after 13:00, the index gradually decreases to 11 at 1 PM and gently tapers off to 9 at 2 PM. By 3 PM, it continues to decline to 6, and by the evening, it reaches a minimal 1 at both 5 PM and 6 PM, finally falling to 0 by 7 PM. This hourly breakdown urges us to protect our skin during the peak hours, especially when the index hits its zenith.
