We recommend visiting Naxos in June or September in order to avoid crowds and to benefit from the best temperatures. Learn more about when to visit Naxos.

Thanks to the Mediterranean climate that guarantees a hot summer season every year, the winters in Naxos are relatively mild, offering to all off-season visitors the opportunity to experience an authentic side of the Cyclades.
Most tourist facilities start operating in mid-May and do not close until the end of October, although it is possible to find accommodation options and places where you can eat during the winter.
