In Mulan, China, understanding the UV Index is crucial for maintaining skin health and preventing sunburn. With the region's climate categorized as Dwb, residents and visitors can expect significant UV exposure, especially during the peak hours of 10:00 AM to 2:00 PM when the UV Index reaches a maximum of 10. Awareness of UV levels not only helps in safeguarding your skin but also empowers you to enjoy the outdoors while effectively managing sun risks. As the index fluctuates throughout the day—from a moderate level of 5 in the morning to an intense 9 and 10 during midday—knowing when to seek shade, wear protective clothing, or apply sunscreen can make all the difference in nurturing your skin's health.

Throughout the year, the UV Index displays significant seasonal changes that influence sun exposure risk. From January to April, the UV Index gradually increases from a low of 2 in January to a high of 6 in April, transitioning from minimal risk to high-risk levels. The summer months of May, June, July, and August pose the greatest hazard, with UV Index values peaking at 10 in July and requiring only 15 minutes of sun exposure before burns can occur. September marks a decline to high levels again (UV Index 6), while October sees a shift back to moderate exposure. The low-risk months return in November (UV Index 2) and December (UV Index 1), allowing for safer outdoor activities. It is crucial for visitors and residents to exercise caution during May to August, employing protective measures such as sunscreen, hats, and sunglasses to mitigate potential harm from UV rays.
