Where to Travel in September
The insider's summer: Europe at its best, the Mediterranean at its warmest, and the crowds gone home.
The straight answer
The best places to travel in September are the Greek islands and Croatia in warm-sea shoulder season, Paris and Rome after the crowds thin, Istanbul and Lisbon in golden weather, and the Serengeti as crossing season winds down.
Ask frequent travelers for their favorite month and September wins more votes than any other. Europe keeps its summer weather and loses its summer crowds: the Mediterranean reaches its warmest swimming temperatures of the year, city break conditions in Paris, Rome, and Barcelona turn ideal, and prices step down from the August peak. The Greek islands and Croatia in September are the reward for waiting.
The rest of the map cooperates. East Africa's river-crossing season runs into September. The northern lights return to Iceland's darkening skies. Seoul and the temperate East Asian cities begin their crisp golden season. New York enters its best stretch of the year. And in New England, the first fall color appears at high elevations by late month.
September's one hard rule: respect the storm map. It is the statistical peak of Atlantic hurricane season, which puts the Caribbean, the Gulf, and Florida into the highest-risk weeks of the year, and it is also peak typhoon season in Japan. The deals are real; so is the reason for them.

The honesty section
Where September works against you
- ✕The Caribbean, Gulf Coast, and Florida. September is the statistical peak of Atlantic hurricane season. This is the highest-risk month of the year to have a beach itinerary on the storm map.
- ✕Japan. Peak typhoon season: September storms regularly disrupt flights and trains, especially across the south and west. October's clear, crisp weather is worth the wait.
- ✕The Maldives and southern India. The southwest monsoon is still running: gray skies, rain, and rougher seas in what should be a postcard. The dry season returns around December.
- ✕Bali and Lombok's peak-price holdouts. Nothing wrong with the weather, but this is a value note: dry season is ending and September still carries near-peak pricing in famous areas. Better rates arrive with the shoulder in October.
Quick answers
September travel FAQ
Where is hot in September?
The Mediterranean is at its warmest-water moment of the year from Greece to Spain, and Lisbon, Istanbul, and southern Italy hold real summer warmth. The Caribbean is hot too, but it is peak hurricane season and priced accordingly.
Where should I avoid in September?
The Caribbean, Gulf Coast, and Florida at hurricane season's statistical peak, Japan during peak typhoon season, and the Maldives while the monsoon lingers.
Is September cheaper than summer for Europe?
Yes. Airfare and hotels step down meaningfully from the July and August peak, especially after the first week, while the weather often improves. September is the best value-to-quality ratio on the European calendar.
When does fall foliage start?
In northern New England and the high Rockies, color typically begins in late September and peaks in early to mid October, moving south and downhill from there. September's final week is the safe early bet for Vermont's high country.
