What to wear in Greece in September

With average daily highs of 84°F (29ºC), you’ll mainly be wearing your summer wardrobe — swimwear, shorts, t-shirts, and light dresses.

UV levels remain high, so you’ll also want to wear plenty of sunscreen.

Experience the Spartathlon

One of the world’s most difficult long-distance races, the annual Spartathlon from Athens to Sparta sees participants follow in the footsteps of Pheidippides, an ancient Athenian long-distance runner.

Runners have 36 hours to run 153 miles (246 kilometers) — roughly the equivalent of six back-to-back marathons.

Traversing rough tracks, vineyards, olive groves, and hillsides before ascending Mount Parthenio (1200m) in the dead of night, Spartathlon sure ain’t for the faint-hearted, but it is quite something to witness.

Island hop

Sitting in shoulder season, Greece ferry schedules are still plentiful and frequent in September, which means it’s a wonderful month to island-hop.

Alternatively, if you prefer to stay in a single spot, you could base yourself on one of the best Greek Islands.
