The best time to go to Megisti is during the shoulder seasons of May, early June, September, and early October.
During these months, the weather is pleasantly warm, ideal for swimming and exploring the island without the intense heat of mid-summer. You'll find the island less crowded than in July and August, allowing for a more relaxed experience at archaeological sites and local tavernas. Flight and ferry services are regular, ensuring convenient travel.
For those who enjoy a lively option and don't mind higher temperatures, July and August offer the full summer experience with all services fully operational and a bustling harbour. This is the peak season for many, with plenty of opportunities for boat trips and evening activities. While busier, Megisti retains its charm, and the warm evenings are superb for dining al fresco.
Travellers looking for a quiet escape might consider late April or late October. The weather can be a bit cooler, but the island is very peaceful, offering a glimpse into local life outside the main tourist season.
