Greece travel guide: best regions for summer weather

Greece offers diverse climatic conditions suitable for various types of travel depending on the season and region. For travelers seeking summer-like temperatures and warm sea water after mid-September, southern islands and the southeast Aegean Sea are the most reliable choices, as northern and western regions experience an earlier transition to autumn with increased rainfall.

Rhodes is highlighted as an ideal destination for late September, with average air and sea temperatures both reaching approximately 26.8°C and low precipitation levels. Crete is also noted for its southern position and large size, making it a safe option for late-season vacations. Other recommended islands for warm water include Kos and Karpathos.

General regional differences include the Ionian Islands, such as Corfu, being greener due to higher rainfall, while Athens experiences a typical Mediterranean climate with hot, dry summers and mild, wetter winters. For those interested in sightseeing, the Peloponnese, Chalkidiki, and Crete offer historical alternatives to beach-focused trips.
