More about September 2026
September marks the turn toward autumn: 319 festivals are listed this month on festt.io, a packed calendar that still stretches the outdoor season into its final weeks while kicking off the return of city stages and indoor venues.
The month is led by major North American names: Lost Lands (215 artists) in Thornville opens the way alongside Louder Than Life (198 artists), Making Time Festival (147 artists) in Philadelphia and Americanafest (171 artists) in Nashville, while Reeperbahn Festival (146 artists) represents Germany on the European side. On the genre front, Rock (200 festivals) and Pop (186) clearly top the bill, ahead of Electro (155).
The United States leads the month with 108 festivals, ahead of France (63), the United Kingdom (27), Germany (25) and Canada (18). After August's summer peak, September offers the last open-air dates before the lineup shifts indoors in October — a good balance between still-mild weather and the cultural back-to-school rush.
