Sifnos is a hilly island in the western Cyclades, with terraced slopes and villages and monasteries dotted across it. Spring winds can still be brisk, but the hills turn green and wildflowers appear everywhere. Days bring around 14 hours of daylight, leaving long, light evenings. Pack summer clothes, a light layer for the evenings and good sun protection. It's a lovely time for walking, with fresh air and green countryside. 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 Sifnos in May

Crowds & Prices in Sifnos in May

Crowds in Sifnos are moderate in May, with plenty of space at the main sights and beaches. Prices are noticeably lower than in high summer, and there's more choice of rooms. Weekdays are calmer than weekends at the most popular spots. Staying slightly outside the main town usually means better value and more space. Booking a few weeks ahead is usually enough.

Ferries to Sifnos from Piraeus and Rafina run more often as the season gets going. 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. Opening hours are long, with many tavernas serving until late.

Festivals & Holidays in Sifnos 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 Sifnos, as across Greece, these traditions are very much alive. 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 Sifnos?

Yes, May is a good month for Sifnos, especially for walkers and sightseers. Expect highs of around 25°C / 76°F, lows near 16°C / 60°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.
