Understanding the UV Index is crucial for residents of Smedby, Sweden, as it helps protect against harmful UV radiation that can lead to sunburn and long-term skin health issues. Knowing your UV exposure levels can empower you to take necessary precautions, especially during peak hours between 12 PM and 2 PM when the UV Index reaches its highest at 6. With Smedby experiencing a Cfb climate, characterized by its mild summers and relatively short sunny periods, awareness of UV levels is essential to enjoy the outdoors safely while minimizing the risk of skin damage.
As the sun rises, the UV Index gradually climbs, reaching its peak at 12:00 PM with an impressive 6.

The afternoon sun maintains its intensity, keeping the index at 6 between 12:00 PM and 1:00 PM.

Always remember to protect your skin during the peak hours!
