What is Lesbos like in spring?
Lesbos in spring, from March to May, is green, flower-filled and mild, the finest season for birdwatching and walking.
Spring, from March through May, is one of the most beautiful times to visit Lesbos, and for nature lovers the very best. After the winter rains the island is at its greenest, the hillsides are carpeted with wildflowers. The air is fresh and mild, making it a notable season for walking, sightseeing and photography.
Above all, spring is the peak birdwatching season, when the Gulf of Kalloni and the island’s wetlands fill with flamingos. Herons and a rich variety of migrating species passing through on their way north, drawing birders from across Europe, especially at the height of the spring passage in late April. This is the single best reason to visit in spring.
The trade-off is the sea temperature, which stays cool in March and April and warms only gradually as the season advances, so early spring is less suited to swimming. Tourism is still slow, however, which means good accommodation deals, uncrowded sights and no competition for taverna tables, making spring ideal for a nature and culture trip.
What is summer like in Lesbos?

The trade-offs of high summer are the heat, which can be intense inland and in the middle of the day. The crowds and prices. Which peak in August when Greeks take their own holidays.

Even at the height of summer, though, Lesbos rarely feels as overwhelmed as the famous Cyclades, thanks to its large size and long coastline. Finding a quiet beach remains easy. The coastal resorts stay cooler than the interior thanks to Aegean breezes. The long summer evenings, when the heat fades and the tavernas fill, are among the great pleasures of the season on the island.

Village festivals, the grape and olive harvests, and the making of ouzo give autumn a rich, authentic flavour, and the tavernas serve the freshest local produce of the year.
Autumn brings a second birdwatching season too, quieter than spring but rewarding, as birds move south through the wetlands. With warm seas, thinner crowds, lower prices and harvest traditions, September and October combine many of the island’s pleasures.

Autumn is the season of harvest festivals, when villages celebrate the grape, olive and ouzo harvests with food, wine and music, offering an authentic taste of island life.
