Understanding the UV Index is essential for residents and visitors of Palaiokastro, Greece, where the Mediterranean climate creates ideal conditions for sun exposure. Being aware of UV levels not only helps in preventing painful sunburns but also plays a crucial role in maintaining skin health over time. With peak UV values soaring to 10 during the midday hours, it's vital to monitor these levels to protect yourself from harmful effects. In this sun-drenched locale, where outdoor activities are common, staying informed about the UV Index is key to enjoying the beautiful weather while prioritizing your well-being.

The heat peaks around 12:00, reaching a blistering 9, and hits its maximum at 13:00 and 14:00, both at a high of 10—a critical time for sun safety. As the afternoon transitions to evening, the UV Index gradually dips; by 18:00, it's down to 2, and as twilight approaches, it settles back at 1 by 19:00. Plan your outdoor activities wisely to stay safe in the sun!
