In Rudsar, Iran, understanding the UV Index is crucial for maintaining skin health and preventing sunburn. As a region with a Mediterranean climate (Csa), Rudsar experiences varying UV levels throughout the day, with peak exposure reaching a high of 10 between noon and 1 PM. This means that during the summer months, the risk of skin damage increases significantly if precautions aren’t taken.

As the sun rises, the UV Index gradually climbs, starting at a modest 1 at 7:00 AM and reaching an energetic 2 by 8:00 AM. The intensity escalates quickly, peaking at a robust 10 between 12:00 PM and 1:00 PM—the ideal time to take extra sun safety precautions! By 2:00 PM, the index begins its gentle decline, settling to 9 at 2:00 PM, and gradually tapering off to a more manageable 3 by 5:00 PM. As evening approaches, the index dwindles to 1 by 6:00 PM, allowing for a calm end to the day. Remember, during peak hours, it’s crucial to protect your skin to enjoy the sunshine safely!
