Mild days, cool nights, and a bumper slate of festivals make September the sweet spot between sweaty summer and holiday crowds. School is back, so Midtown lines ease, yet the city hums with Fashion Week runways, Broadway Week bargains, and the Feast of San Gennaro’s cannoli scent drifting up Mulberry Street. Aim for early-morning strolls—sunrise is after 6am—and book UN-week hotels well ahead; presidents in town mean security zones and price hikes.
