Heat and rain. In the December-to-April dry season the mornings are merely warm and the afternoons are punishing. March, April and May are the hot months, with April usually the peak; February is one of the kinder ones. The wet season conventionally runs from about May to November, and October and November are among the wettest — plan a November trip as a rainy one, whatever the "dry from December" shorthand implies. When it rains, it generally comes in the late afternoon, hard, and typically for about an hour. Neither pattern is a reason to stay in; both are reasons to front-load the day.
Traffic. The two crushes are generally around seven to nine in the morning and half four to seven in the evening. A Grab motorbike will beat a car by a wide margin in either, and costs a fraction of one. A car is worth it in rain, with luggage, or in Cholon, where the wholesale streets are genuinely chaotic.
Crossing the road. Step off the kerb, walk slowly and at a constant speed, and do not stop, hesitate or run. Riders read your trajectory and flow around you. The standard advice here is that stopping halfway is the thing most likely to get you hurt, and everything I have watched at these junctions supports it.
The metro. Line 1 opened in December 2024 and runs from Bến Thành out to Suối Tiên, fourteen stations, around thirty minutes end to end, with three underground stops in the centre. For a visitor, Bến Thành, Opera House, Ba Son and Thảo Điền are the useful ones; the rest of the line serves commuters rather than sightseers, and it is worth taking that literally when you plan. Fares are modest — expect a small fraction of what a taxi costs — and payment methods have been changing, so check what the machines and gates accept when you arrive. It does not go to Cholon, which is west; the line runs east.
Names. Since July 2025 Vietnam has abolished district-level administration, and the old District 1 has been split between wards called Sài Gòn, Bến Thành, Tân Định and Cầu Ông Lãnh. Nobody says this out loud. Taxi drivers, hotels and every conversation you will have still use "District 1", "District 3", "District 5". Book by neighbourhood name and you will be fine.
Tết. The lunar new year, falling in late January or February depending on the year, empties the city and closes family businesses for days. It is a fascinating time to be here and a difficult time to eat. Check the date before you book.
From about 6.30am. Get up and eat properly. Breakfast is a real meal here and it happens early: a bowl of phở, or a bánh mì from a cart, and an iced coffee thick with condensed milk. By around nine many of the better breakfast places are typically winding down or simply sold out, so this is not a city that rewards a lie-in.
From about 8am. Start at the Reunification Palace, which generally opens around eight; confirm the day's hours, since it occasionally closes for state functions. Allow an hour and a half. The 1960s interiors are the draw — the map room, the cabinet chamber, the frozen-in-amber banqueting suite — but the basement is the reason to come: a warren of concrete command rooms, radio equipment and telephone exchanges left more or less as they were.
Roughly 9.45am. Walk to the War Remnants Museum, about seven hundred metres away, ten minutes at a slow pace. Give it two hours. It is an unambiguously Vietnamese account of the war and does not pretend otherwise; the photojournalism gallery and the sections on chemical defoliants are genuinely distressing, and I would not take a young child. Go in the morning while you still have the composure for it.
From about noon. Eat, then get out of the sun until half past three. This is not laziness, it is the plan. The Museum of Fine Arts occupies an early-1930s mansion built for the Hui Bon Hoa family, with tiled courtyards, a caged lift and stairwells open to the air — understand that this is shade rather than climate control, since the galleries run off those courtyards, but it is genuinely out of the sun and the building is at least as good as the collection. The Southern Women's Museum is the other option, and is quieter than it deserves to be. If what you actually need is cold air, a long coffee in a shophouse café is the honest answer, and a perfectly respectable use of an afternoon.
From about 3.30pm. Walk the colonial spine. The Notre-Dame Cathedral Basilica has been under restoration since 2017 and the completion date has been pushed back repeatedly; the target at the time of writing is around 2027. Interior access has been restricted throughout, so plan on seeing an exterior and check locally if you had hoped to get inside. Opposite, the Central Post Office is still a working post office, barrel-vaulted and green-shuttered, its design often attributed to Gustave Eiffel although historians dispute that. Beside it, the pedestrianised book street is a pleasant ten minutes.
From about 5.30pm. Drift down Đồng Khởi to the Opera House, then onto Nguyễn Huệ, the wide pedestrian plaza running down to the river. To my eye this is the city at its most sociable: skateboarders, wedding photographers, entire extended families out in the cool. The old apartment block on its eastern side, now stacked floor upon floor with cafés and bars, is worth climbing for the view back down the plaza.
Evening. Dinner, then a decision. Bùi Viện, the backpacker strip, is loud, neon and relentlessly touristed; give it twenty minutes for the spectacle and leave. I would rather walk over the Ba Son bridge to Thủ Thiêm and look back at the skyline from the empty side of the river, which costs nothing and is, to me, the better hour.
