From September to November Hanoi shifts from summer humidity to cooler mornings around Hoàn Kiếm Lake, and you'll notice school uniforms and áo dài appearing more often on the pavements.
Autumn in Vietnam is split: the Red River Delta settles into dry, clearer weather by October, the central coast — provinces such as Thừa Thiên–Huế and Quảng Nam — remains prone to typhoons and river flooding through October, and the Mekong Delta moves slowly from the wet season toward its drier months by November.
The Reunification Express between Hà Nội and Sài Gòn still takes about 30 hours if you choose the rail route; faster options are plentiful because domestic carriers run frequent, inexpensive flights between Vietnamese cities, and intercity buses fill gaps where trains don’t stop.
On the ground a majority of short trips are on motorbike or by Grab; expect to pay in Vietnamese đồng for street stalls and floating markets, while cards work at larger hotels and many restaurants in city centres.
In Vietnam autumn deepens the season for pho in the north—Hà Nội stalls do heavy morning trade—and cafés switch from iced cà phê sữa đá to more phin-brewed hot coffee and Hanoi’s egg coffee reappears on many menus.
Meals still follow local routines: breakfast in public near markets, later family dinners in the suburbs, and street vendors running late into the evening on city sidewalks throughout Vietnamese towns.
Expect to remove shoes in private homes and some pagodas, accept that bargaining in markets is normal in Vietnamese bazaars, and know that a small tip at a taxi or for a particularly helpful guide is appreciated though not compulsory.
What you need to enter Vietnam, for the passport you hold.
