Weather in Nisyros in April
Expect mild, fairly changeable weather in Nisyros in April, spring. Expect highs of about 20°C / 68°F and overnight lows near 14°C / 58°F. Rain falls on around 5 days, adding up to about 44 mm over the month. The sea averages about 17°C / 63°F, cold enough that only hardy swimmers go in. Spring winds can still be brisk, but the hills turn green and wildflowers appear everywhere.

Pack layers, including a warm sweater for the evenings and a light waterproof jacket. Mornings and evenings are noticeably cooler than the middle of the day. It's a lovely time for walking, with fresh air and green countryside. Plan outdoor time around the middle of the day, when it's at its warmest.
Swimming in Nisyros in April
At around 17°C / 63°F, the sea in Nisyros is too cold for most people to swim in April. Save swimming plans for July, August and September, when the water is much warmer. Beaches are empty and unstaffed in winter, so swim only in calm conditions. Shallow, sheltered bays feel a little warmer on still, sunny afternoons. A wetsuit makes a big difference if you want to get in.
Crowds & Prices in Nisyros in April
You'll have Nisyros largely to yourself in April. Prices are at their lowest of the year, although fewer hotels are open.

It's a good time to see everyday life, away from the summer bustle. You can usually book at short notice.

Boat trips and excursions run regularly, weather permitting.
Festivals & Holidays in Nisyros in April
Greek Easter often falls in April, and it's the biggest celebration of the year, with candlelit processions on Good Friday, midnight services on Saturday and lamb roasting on Sunday.

Locals in Nisyros mark these dates in the traditional way, and visitors are welcome to join in.
Is April a Good Time to Visit Nisyros?
April is a good time for Nisyros if you're coming for walks, sightseeing and walking into the volcano, not the beach. Expect highs of around 20°C / 68°F, lows near 14°C / 58°F and rain on around 5 days. The countryside is green, it's quiet and prices are low, but the sea is too cold for most people and the season is only just starting. For swimming, wait until June, September, October or November.
