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.

We also suggest bringing a long-sleeved shirt, shawl, or cardigan for the evenings. While the temperatures don’t drop off too much, it’s best to be prepared so you can sip al fresco sundowners free from goosebumps.

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.
