The best time to visit Alissos is during the shoulder seasons of late spring (April to May) and early autumn (September to October), when the weather is pleasant and the crowds are smaller.For travelers looking for warm weather for beach activities and water sports, the summer months of June through August are ideal. Temperatures are at their highest, making it superb for enjoying the Ionian Sea, though this is also peak tourist season, so expect more people and higher prices.Couples seeking a peaceful retreat will appreciate the quieter shoulder seasons. The weather is still warm enough for exploring the countryside, visiting ancient Olympia without the summer heat, and enjoying local tavernas without the bustling crowds.
