Frequently Asked Questions
What time does the sun set in Chalkidiki in September?
Through September, sunset in Chalkidiki moves from around 8:00 pm to around 7:10 pm in Greek local time, as the evenings get shorter. In mid-September, expect it at around 7:35 pm. Evenings cool quickly after sunset, so bring a layer.
Is it still warm in Chalkidiki in September?
Yes. September is warm and mostly sunny, and the sea is still warm enough for swimming, especially early in the month. It cools down faster than southern Greece, though, and by late September evenings can be fresh and showers more likely.
Can I take a boat cruise along Mount Athos in September?
Yes. Boat trips to the Mount Athos cruise run regularly in September, but they're busy, so book ahead or take the first departure of the day. Trips can still be cancelled on very windy days. Cruises leave from Ouranoupoli and stay offshore, since only men with a special permit may enter the monastic state.
Do I need a car in Chalkidiki in September?
Yes. Chalkidiki spreads over three long peninsulas, and buses from Thessaloniki mainly serve the bigger resorts, so a car is by far the easiest way to get around. In September, book early, as rental cars can sell out.
Is September or October better for visiting Chalkidiki?
September, if the beach matters, as the sea is still warm. October is quieter and great for sightseeing and walking, but the weather becomes more changeable and seasonal businesses start to close.
