In Kostino, Russian Federation, understanding the UV Index is crucial for maintaining skin health and preventing sunburn. With the city experiencing a Dfb climate—characterized by warm summers—residents and visitors are exposed to varying UV levels throughout the day. Awareness of daily UV fluctuations can help individuals take necessary precautions during peak hours, particularly when the index reaches a maximum of 6 at midday. By staying informed about UV exposure risks, you can enjoy the sun safely while minimizing the potential for skin damage.
As the sun rises, the UV Index begins its ascent, peaking between 10 AM and 1 PM at a solid 6, indicating a moderate risk of harm from unprotected sun exposure. Early birds can enjoy the sun safely at 7 AM with a lower 3, but as the day progresses, from 8 AM to 9 AM, it climbs to 4 and 5 respectively, urging caution. Although the intensity remains steady at 6 until 1 PM, it starts to taper off thereafter, falling to 5 at 2 PM, and further declining to 3 by 3 PM. As the evening approaches, the UV Index settles down to 2 at 4 PM and further diminishes to 1 by 6 PM, providing a gentle reminder to enjoy the outdoors but prioritize sun safety during peak hours!
