September is arguably the best month to be in Pittsburgh, as the oppressive summer humidity gives way to crisp, comfortable air and an abundance of sunshine. The city is energized by the return of university students and the start of Steelers football season, creating a vibrant buzz around town. It's the perfect time for a long walk through the Oakland neighborhood or a bike ride along the riverfront trails. The primary pain point for visitors in September is being unprepared for the significant temperature drop after sunset. A perfectly warm afternoon can turn into a surprisingly chilly evening, catching anyone dressed only in shorts and a t-shirt off guard, especially while sitting in the stands for a late-season Pirates game at PNC Park.
