Bordered by the North Aegean Sea, Mytilene boasts a warm, Mediterranean climate. Temperatures often exceed 30℃ in July and August, while sea temperatures tend to peak at 24℃ in August.
If you’re looking to take advantage of the sunshine at the beach, those are the best months to go. Just remember that, as it’s peak tourist season, you’ll need to get up early for a good spot on the sand.
If you want to enjoy the beaches without the crowds, it would be better to plan your trip to Mytilene for spring and autumn. Temperatures hover around 15℃ to 19℃, and with the sea at 16℃, you can still go for a slightly chillier dip.
If the beaches aren’t the main draw for you, and you would rather visit Mytilene at a lower cost, winter is an excellent alternative. Temperatures sit around 10℃ to 13℃, amiable for a stroll through Mytilene’s narrow streets. The rainy days are ideal for trips to the island’s museums.
