Weather in Lemnos in May
In Lemnos, May brings late-spring weather that is pleasantly warm and mostly dry. Daytime highs average around 22°C / 72°F, and nights drop to about 15°C / 59°F. Sea temperatures average around 18°C / 64°F, bracing, and too cool for many swimmers. Rain is rare, with only 2 wet days in an average May. Lemnos is a low, volcanic island in the north Aegean, with open landscapes and few trees to block the wind. Weather fronts become rarer as the season goes on, and calm, clear days take over.

Mornings and evenings are noticeably cooler than the middle of the day. The weather can change from one day to the next, so check the forecast before planning a long day out. It's comfortable to be out all day, though the midday sun is still strong.
Swimming in Lemnos in May
Swimming in Lemnos in May is possible but bracing, with the sea at around 18°C / 64°F. Save swimming plans for July and August, when the water is much warmer. Beach facilities are only partly open at this time of year. The water is famously clear, which makes it great for snorkeling. If you feel the cold, a wetsuit top makes a difference.
Crowds & Prices in Lemnos in May
May is a shoulder month in Lemnos, busy enough to feel lively but well below the summer peak. Hotel rates sit between the winter lows and the summer peak. Staying slightly outside the main town usually means better value and more space. Weekdays are calmer than weekends at the most popular spots. A few weeks' notice is usually enough to find a good room.
What's Open in Lemnos in May
Ferries to Lemnos from Lavrio and Kavala run more often as the season gets going. The island also has an airport with flights from Athens. By May, almost everything has reopened for the season. Archaeological sites and museums are on their longer summer hours. Most sites close on Easter Sunday and 1 May. Shops in tourist areas often stay open into the evening.
Festivals & Holidays in Lemnos in May
1 May is a public holiday, when many Greeks head out to the countryside and make wreaths of spring flowers. Greek Easter sometimes falls in early May, and Whit Monday, fifty days later, is another long weekend. In Lemnos, these occasions are celebrated much as they are across the rest of Greece. Between the big dates, it's a good time to join in local life, from markets to name-day celebrations.
Is May a Good Time to Visit Lemnos?
Yes, May is a good month for Lemnos, especially for walkers and sightseers. In numbers: highs of about 22°C / 72°F, lows of 15°C / 59°F and rain on around 2 days in a typical May. The countryside is at its best and it's comfortably warm, but the sea is still refreshing rather than warm. It suits active travelers and anyone avoiding the peak season. For warmer water with fewer crowds, June or September would be the better bet.
