Understanding the UV Index in Kiato, Greece, is essential for protecting your skin and overall health under the Mediterranean sun. With peak UV levels reaching as high as 11 around midday, awareness of these fluctuations can help you prevent sunburn and reduce the risk of long-term skin damage. Kiato’s warm, CSA climate brings high UV exposure, particularly during summer when outdoor activities are abundant. Being informed about the UV Index not only aids in making healthier choices but also enhances your enjoyment of the beautiful sunny days this charming coastal town has to offer.
During the day, the UV Index exhibits a striking pattern as it peaks in the late morning and early afternoon. Starting from a modest value of 1 at 07:00, the index gradually climbs, reaching 3 by 09:00. Expect a sharp increase around 10:00, when it soars to 5, and it doesn't stop there; by noon, it hits an impressive 10. The highest point of the day occurs at 13:00, with a peak of 11, indicating a critical time for sun exposure. As the afternoon progresses, the index begins to decline, falling to 10 at 14:00 and tapering off to 9 at 15:00. By evening, the UV Index diminishes steadily, finishing the day back at 1 by 19:00. This data emphasizes the importance of protective measures during the high noon hours when UV levels are at their most intense.

September sees a slight decline in UV levels but remains high (Index 8), while by October, it decreases to high (Index 7) with a burn time of 25 minutes. During the winter months, January, February, and December, UV levels return to moderate (Index 3 to 5), allowing for more extended outdoor activities with a burn time of 30 minutes. As a general guideline, individuals are advised to wear sunscreen, protective clothing, and seek shade during peak UV hours from spring through summer to mitigate health risks.
