Hanoi in April
Often named a good month to visit along with March. Some drizzle lingers but warmer temperatures make walking easy. The Hung Kings commemoration falls on the tenth day of the third lunar month, a public holiday that usually lands in April. April 30 and May 1 run together for a holiday feel.
Days averaged 28°C and nights 22°C. Midday was for air conditioning, a cold drink or a long lunch out of the sun. About 10 days a month saw rain, enough that a wet-weather plan was worth having. A visitor in 2007 met 6 rain days; one in 2021 met 18. The average of 10 hid that gap.
11 days past 30°C made it a month for early starts and a long lunch indoors. Not every year was typical: 2024 ran 3.5°C warmer than the mean, with highs of 31.8°C.
