With a humid subtropical climate, Shanxi experiences significant UV exposure throughout the day, peaking at an alarming 11 between 12:00 PM and 1:00 PM.

Seasonal UV changes indicate a significant increase in UV Index from January to July, with the highest levels occurring during the summer months of May to July, which are categorized as extreme (UV Index levels 11-13). The high-risk months for UV exposure are March through August, particularly when UV levels reach very high and extreme ranges. During these periods, burn times are notably short, with only 10-15 minutes recommended for safe sun exposure. Visitors and residents should take precautions by wearing sunscreen, protective clothing, and seeking shade during peak sunlight hours to minimize the risk of skin damage. As the year progresses into October and November, UV exposure decreases, but caution should still be maintained in January and February, where high UV levels persist.
