The best time to visit Kea is during the spring, June and early autumn. During these months, the weather is pleasantly warm, the island is lush with greenery, and it's less crowded compared to the peak summer season. This is ideal for exploring the island’s beaches, hiking trails, and historical sites. If you enjoy vibrant beach life and bustling local events, July and August are also great months to visit, although the island will be busier.
