Understanding the UV Index in Sami, Greece, is crucial for maintaining skin health and preventing sunburns, especially during the sun-drenched summer months. With a Mediterranean climate typical of the region, UV levels can soar, peaking at a 10 around midday. This emphasizes the need for residents and visitors alike to be aware of UV exposure risks throughout the day—from a low of 1 in the early morning to an intense 10 in the early afternoon. By keeping an eye on the UV Index, individuals can take necessary precautions to protect their skin and enjoy the glorious sun safely.
As the sun rises, the UV Index begins to climb, starting at a gentle 1 at 7:00 AM and remaining steady through 8:00 AM. By 9:00 AM, it nudges up to 2, but as the day progresses, the intensity skyrockets. At 10:00 AM, it hits 4, and by midday, the UV Index soars to a peak of 10 at both 1:00 PM and 2:00 PM—a clear indication to seek shade and wear sunscreen. After this peak, it gradually dips to 9 by 3:00 PM, continuing its descent to 5 at 5:00 PM, and finally, the UV levels soften to 1 as evening falls at 7:00 PM. This day exemplifies the sun's potent rays, reminding us to stay vigilant during those peak hours!

September marks a slight decrease to 8, while October sees a return to high levels at 6, before falling back to moderate in November and December.
