The best time for swimming is July, August and September, with August usually the warmest. Beaches like Masouri are still worth a visit for the scenery and a walk along the shore.

Crowds & Prices in Kalymnos in April
Tourism in Kalymnos slows right down in April. Prices are at their lowest of the year, although fewer hotels are open. If Greek Easter falls during your trip, expect busier ferries and higher prices over that weekend. It's also climbing season, so rooms near Masouri can be surprisingly busy. Tavernas that stay open cater mainly to locals, which is often when the food is best. Last-minute bookings are rarely a problem.
What's Open in Kalymnos in April
Ferries to Kalymnos from Piraeus and Kos run more often as the season gets going. The island also has an airport with flights from Athens. Many businesses reopen during April, often in time for Easter, but some wait until May. Archaeological sites and museums are on their longer summer hours. Most sites close on Easter Sunday. Boat trips and excursions run regularly, weather permitting.
Festivals & Holidays in Kalymnos in April

Kalymnos celebrates Easter with a bang, literally, as locals set off homemade explosions in the hills. Many businesses close on Good Friday afternoon and Easter Sunday, and lots of Greeks travel to their home villages for the holiday.
Is April a Good Time to Visit Kalymnos?
April is a good time for Kalymnos if you're coming for walks, sightseeing and climbing its famous crags, not the beach. Expect highs of around 20°C / 67°F, lows near 12°C / 53°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.
