Understanding the UV Index is crucial for residents and visitors of Köse, Turkey, where the climate tends to be diverse and conducive to both outdoor activities and sun exposure. As UV levels can reach dangerously high numbers—peaking at 12 around noon—being aware of these fluctuations is essential for preventing sunburn and protecting your skin health. In Köse, the Dfb climate brings distinct seasons, but summer days often present considerable UV risks, making it imperative to safeguard against overexposure during peak hours.

To enjoy outdoor activities safely, it’s crucial to stay mindful of these fluctuating UV levels throughout the day, particularly in the late morning and early afternoon hours.
