With UV levels reaching a peak of 10 during midday hours, awareness can help you prevent sunburn and reduce the risk of long-term skin damage. Located in a Cfa climate zone, Yuanzhu experiences varied weather patterns that contribute to higher UV radiation levels, particularly in the summer months.
