In Yaroslavl, Russian Federation, staying informed about the UV Index is vital for protecting your skin from harmful ultraviolet rays. Understanding UV levels helps in taking proactive measures to prevent sunburn and maintain overall skin health. Yaroslavl experiences a Dfb climate, which means that while summers can bring pleasant warmth, the mid-afternoon sun can often elevate UV levels to a maximum of 7—a risk factor that shouldn't be overlooked. By keeping an eye on the UV Index, residents and visitors can enjoy the sunshine safely while minimizing the risk of skin damage and long-term health issues.
As the day unfolds, the UV Index rises steadily, peaking at 7 between 12:00 and 13:00. Early risers at 07:00 will experience a moderate 2, perfect for a leisurely morning stroll. By 09:00, the index climbs to 4, indicating it’s time for some sun protection. The warmth intensifies by 10:00 and 11:00, maintaining a high 6, before reaching its zenith at 12:00 and 13:00. As afternoon approaches, UV levels begin to ebb, dropping to 5 at 15:00 and cooling to 4 by 16:00. Finally, the evening settles in with comfortable levels of 2 at 17:00, tapering off to a gentle 1 by 18:00 and 19:00. Remember, when the sun is at its fiercest, it’s wise to take precautions!
