Understanding the UV Index is crucial for residents and visitors of Bardiya, Nepal, where the tropical climate often results in high levels of sun exposure. Monitoring UV levels is essential for preventing sunburn and maintaining skin health, especially during peak hours when exposure risks are highest. With UV Index values peaking at 12 around noon, it’s vital to take precautions to protect your skin from harmful rays. As Bardiya experiences a Cwa climate, the sun can be intense, making awareness of UV levels not just beneficial, but necessary for a healthy lifestyle. Stay informed and enjoy the sun safely!
