Here are the festivals and events that happen each September in the USA.
Beginning September 15 - National Hispanic Heritage Month. The time between September 15 and October 15 has been designated in the U.S. as National Hispanic Heritage Month. Schools, museums, and other venues use the time to educate others on Hispanic culture in the United States and significant contributions by Hispanic-Americans.
First Monday in September - Labor Day. This public holiday marks the unofficial end of summer. Many Americans take their last vacations of the summer over Labor Day Weekend, so expect hotels and inns near beaches to book up quickly. Labor Day is akin to "May Day," the holiday celebrated by many around the world to salute workers.
Many big events take place on Labor Day Weekend since it is considered summer's last hurrah.
September 11 - Patriot Day. While this is not (yet) a federal holiday, September 11 is considered a day of remembrance for the thousands who perished in the attacks of September 11, 2001, in New York City, Washington, DC, and Shanksville, Pennsylvania. The most obvious setting for commemorating 9/11, which is also called "Patriot's Day," is at the three memorials dedicated to the victims of the attacks on that day.

Mid-September - Kentucky Bourbon Festival. Bardstown, Kentucky, is known as the Bourbon Capital of the World. As such, the town holds the annual Kentucky Bourbon Festival to celebrate the caramel-colored libation. If you are a fan of whiskey, this is a unique fair to visit.
Mid-September - Grapefest. A favorite festival in Texas since 1986, Grapefest is a grape-harvesting and wine festival that features grape stomping contests, wine tasting, live music, and the world's largest consumer-judged wine competition in the nation.
Mid- to Late-September - Oktoberfest. This festival of German origins is celebrated with gusto in many parts of the United States, particularly by German beer and bratwurst lovers. Learn more about where to celebrate Oktoberfest in the United States.
