September can be a wonderful time to visit Mexico, particularly for travelers who prefer a quieter experience. With the summer vacation crowds dispersing, you can savor more popular destinations without the throngs of tourists.
However, along the beaches, September to mid-October is hurricane season – you’ll usually get wet weather, choppy seas and mosquitoes if not a full-on tropical storm.
Prices may drop during the “shoulder” seasons – mid-September to early November and late April to early June – and the best deals are usually available during the low season (November to March, excluding Christmas and New Year).
