Understanding the UV Index is crucial for residents and visitors in Yuli, China, where the BWk climate can lead to significant sun exposure. With peak UV levels reaching as high as 10 during midday hours, awareness of UV intensity is vital for preventing sunburn and safeguarding skin health. Knowing the daily UV patterns helps you take appropriate precautions, especially during the hottest hours, ensuring that you enjoy the sunny days without risking your well-being. As Yuli experiences varying UV exposure throughout the year, being informed can empower you to protect your skin and enjoy the outdoors safely.

Throughout the year, the UV Index displays significant seasonal changes that are crucial for both visitors and residents to understand for effective sun protection. From January to February, UV levels are relatively low to moderate, with burn times extending from 45 minutes to 30 minutes. However, as spring approaches in March, the UV Index rises to 6 (high exposure category), reducing burn time to 25 minutes. The highest risk occurs during the summer months of April to August, where the UV Index peaks at 10 (very high) and burn times diminish to just 15 minutes. This pattern necessitates heightened caution during these months, particularly from April to September. As autumn sets in, UV levels decrease once more, with October showing a moderate index of 5 (30-minute burn time) and November returning to a moderate 3 (with a burn time of 30 minutes). By December, the UV Index drops back to 2, allowing for longer exposure without immediate risk. Visitors and residents are strongly advised to apply sunscreen, wear protective clothing, and seek shade, particularly during the high-risk months from April to August, to prevent skin damage.
