Understanding the UV Index is crucial for residents and visitors of Yajia, China, where sunny days are plentiful, particularly in its Cfa climate zone. With UV levels rising sharply throughout the day, peaking at an intense 12 around noon, it's vital to be aware of how these rays can impact your skin health.
