Best time to visit Hanoi

Hanoi is a city of two halves. December scores 92 and June scores 35 — a 57-point swing, which is the difference between a holiday and an endurance test. The month you pick matters more here than almost anywhere. 4 of the twelve months sit within ten points of the best, so there is more than one right answer.

June is the warmest month at 32.8 °C and January the coolest at 21.3 °C — a 11.5 °C spread across the year. 181 days a year top 30 °C, more than a third of the calendar, so heat is the baseline here rather than a season.

There is a real wet season here. June to August carry the rain — up to 24 wet days in a month — while January, February, November and December drop as low as 4. That 20-day gap is the biggest single difference between a good month and a bad one in Hanoi, and it moves further than the temperature does.

Daylight runs from 10.9 hours in winter to 13.4 in summer, enough to notice on a sightseeing itinerary.

The three strongest months are December, January, February. The one to think twice about is June. Each month below has its own page with rainfall reliability, extremes, daylight and crowd levels.
