Weather in Hydra in May

In Hydra, May brings late-spring weather that is warm and mostly dry. Average highs reach 25°C / 77°F, with lows of around 16°C / 61°F. Rain is rare, with only 2 wet days in an average May. The sea averages about 19°C / 66°F, bracing, and too cool for many swimmers. Spring arrives early here, with green hills, blossom and plenty of calm, sunny days. Hydra is a rocky, car-free island, and the steep lanes around the harbor can feel hot when the air is still. Daylight lasts about 14 hours, leaving long, light evenings. Pack summer clothes, a light layer for the evenings and good sun protection. The weather can change from one day to the next, so check the forecast before planning a long day out. It's a lovely time for walking, with fresh air and green countryside. It's pleasant to be outside from morning to evening, with sun protection at midday.

Swimming in Hydra in May

Swimming in Hydra in May is possible but bracing, with the sea at around 19°C / 66°F. Save swimming plans for July, August and September, when the water is much warmer. Good spots include Vlychos and Bisti. Beach facilities are only partly open at this time of year. Many coves are rocky or pebbly, so water shoes are useful. A short wetsuit helps if you feel the cold.

Crowds & Prices in Hydra in May

Crowds in Hydra are moderate in May, with plenty of space at the main sights and beaches. You'll find better deals on rooms and car hire than in July and August. Weekends are busier than weekdays, as it's a popular escape from Athens. The busiest spot is the harbor when day-trip boats arrive; for more space, stay overnight and enjoy the evenings, once the day-trippers leave. Booking a few weeks ahead is usually enough.

What's Open in Hydra in May

Ferries to Hydra from Piraeus run more often as the season gets going. Nearly all hotels, tavernas and beach bars are open by May. Archaeological sites and museums are on their longer summer hours. Most sites close on Easter Sunday and 1 May. Boat trips and excursions run regularly, weather permitting. Opening hours are long, with many tavernas serving until late.

Festivals & Holidays in Hydra in May

Greek Easter sometimes falls in early May, and Whit Monday, fifty days later, is another long weekend. 1 May is a public holiday, when many Greeks head out to the countryside and make wreaths of spring flowers. In Hydra, as across Greece, these traditions are very much alive. Weekends bring family outings and long lunches, and the evenings grow livelier as the days lengthen.

Is May a Good Time to Visit Hydra?

Yes, May is a good month for Hydra, especially for walkers and sightseers. Expect highs of around 25°C / 77°F, lows near 16°C / 61°F and rain on around 2 days. 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, September or October would be the better bet.
