Understanding the UV Index is crucial for residents and visitors in Koronos, Greece, where the Mediterranean climate brings plenty of sunshine and outdoor activities. By being aware of UV levels, you can effectively prevent sunburn and protect your skin health—essential considerations for enjoying the beautiful landscapes of this charming village. During the warmest months, UV exposure can reach a maximum of 10 around midday, indicating a high risk of harm from unprotected sun exposure. With Koronos' warm and sunny climate, staying informed about UV Index readings will help you enjoy the sun safely while minimizing the risk to your skin.
At dawn, 7:00 AM, the UV Index is a mild 1, offering a gentle start to the day. As the sun climbs higher, it steadily rises, reaching 2 by 8:00 AM and hitting 3 at 9:00 AM. However, between 10:00 AM and 1:00 PM, the intensity increases sharply, peaking at an impressive 10 from 12:00 PM to 1:00 PM—the highest level of risk. The UV Index then begins its descent, dropping to 8 at 3:00 PM, followed by a gradual decline to 4 by 5:00 PM. As evening approaches, the index wanes further, settling back down to 1 by 7:00 PM. To enjoy the sunshine while staying safe, make sure to take precautions, especially during those peak hours!
