Oktoberfest in Munich is actually held mostly in September because the weather is slightly warmer, proving that even the most deeply held Bavarian traditions will happily bend to the practicalities of outdoor drinking.

Why Munich’s Oktoberfest Starts in September

The name preserves the festival’s origin, but the calendar reflects a practical choice. Munich’s Oktoberfest began in 1810 as a public celebration of the marriage of Crown Prince Ludwig and Princess Therese. The festivities included horse races on a field outside the city, later known as the Theresienwiese—the “Theresa meadow,” now commonly shortened to the Wiesn.

The celebration proved popular enough to return, gradually growing into a much larger annual fair. As organizers extended its run, they favored the milder, often more dependable days of late summer and early autumn. Starting in September gives visitors more comfortable conditions for spending long hours outdoors, while the final days can still reach into October. The festival therefore keeps its historic name without being confined to October dates.

A Festival Built Around an Open Field

That seasonal choice matters because Oktoberfest is not just a beer celebration indoors. Its large tents, rides, food stalls, and crowds spread across the Wiesn, where weather affects nearly every part of the experience. A warmer start to the season makes outdoor dining and walking between attractions more inviting; colder or wet weather can make the same sprawling fair less comfortable.

The site itself keeps the original celebration close to the city’s memory: the Wiesn is named for the bride whose wedding prompted the first festivities. What began as a royal occasion became a recurring public gathering, and its calendar evolved to suit the practical demands of an outdoor event. Oktoberfest’s September start is a small adjustment that helped an October-named tradition thrive.
