Understanding the UV Index is crucial for the residents and visitors of Khersonisos, Greece, where the Mediterranean sun shines brightly, especially in summer months. With UV levels peaking between 10 AM to 3 PM, awareness of these values can play a key role in preventing sunburn and safeguarding skin health. Given Khersonisos’s warm Csa climate, the risk of overexposure increases significantly, making it vital to monitor daily UV readings. By staying informed, you can enjoy the beautiful beaches and outdoor activities while minimizing the risks associated with harmful UV rays.
The UV Index reveals a dynamic ascent and descent throughout the day, peaking with intensity during midday. Starting at a gentle 1 at 7:00 AM, it climbs steadily, reaching 10 by 1:00 PM and maintaining this highest level until 2:00 PM. This critical window indicates significant sun exposure, and it’s essential to take precautions. As the afternoon progresses, the index begins to taper off, dropping to 8 at 3:00 PM, then gradually falling to 1 by 7:00 PM. This data highlights the importance of being sun-smart during the peak hours to minimize UV exposure risks.
