Understanding the UV Index in Balvi, Latvia, is crucial for safeguarding your skin health and preventing sunburn. The UV Index measures the strength of ultraviolet radiation on a scale from 0 to 10+, providing essential information for anyone venturing outdoors. In Balvi's Dfb climate, typical UV exposure can peak between 11:00 AM and 2:00 PM, when values reach 7, indicating high risk for harm if protective measures aren't taken. By staying informed about UV levels, you'll be better equipped to enjoy the beautiful Latvian outdoors while protecting your skin from potential damage.
