Understanding the UV Index in Yunhe, China is crucial for safeguarding your skin against harmful ultraviolet rays. As a region that experiences a subtropical highland climate, Yunhe is exposed to varying UV levels throughout the day, particularly peaking between 12:00 PM and 3:00 PM when the UV Index can soar to 15. By tracking these levels, residents and visitors can take proactive measures to prevent sunburn and protect long-term skin health. Being aware of the UV Index not only helps in planning outdoor activities but also encourages the adoption of sun-safe practices essential for enjoying the beautiful sunshine of Yunhe without compromising skin safety.
As the sun rises, the UV Index starts low at 1 by 7:00 AM, making it a safe time for outdoor activities. However, as the day progresses, there's a notable surge in UV radiation. By 10:00 AM, the index spikes to 7, escalating to a striking 14 at 12:00 PM. The peak occurs at 1:00 PM, reaching 15, which signals a high risk for skin damage without protection. Fortunately, the intensity begins to taper off in the afternoon, dropping to 9 by 4:00 PM and gradually dwindling to 1 by 7:00 PM. Thus, while the morning may welcome you with mild UV exposure, the midday sun demands caution. Remember your sunscreen! 🧴🌞

The high-risk months for UV exposure are from March to October, where the UV Index consistently reaches extreme levels of 11 to 15, with a particularly critical period from May to August. During these months, the recommended burn time is a mere 10 minutes, urging both visitors and residents to take substantial precautions against skin damage. As the seasons transition into late autumn and winter, the risk decreases, with lower UV Index levels in January, February, November, and December, although the very high readings in February and November still warrant attention.
