Understanding the UV Index is crucial for residents and visitors to Dayang, China, where the subtropical climate brings both sunny days and potential UV exposure risks. With UV levels peaking at a striking 13 around noon, awareness can make all the difference in preventing sunburn and protecting your skin health. As the sun rises higher in the sky, daily UV readings can fluctuate significantly, highlighting the importance of checking the index to stay safe outdoors. Whether you're enjoying the scenic views or engaging in outdoor activities, knowing the UV Index in Dayang is essential for safeguarding your skin against harmful rays.

By the afternoon, it slips down to 6 at 15:00, then diminishes further to 2 at 17:00 and finally to a mere 0 as twilight descends at 19:00. It's clear that the highest risk for sun exposure occurs midday, making it essential to protect your skin during those peak hours!
