The best time to go to Hai Phong is during the dry season, which runs from October to April, with October and November, and then March and April, offering the most pleasant conditions.During these months, you'll experience comfortable temperatures, typically ranging from 20°C to 28°C, and significantly less rainfall. This makes it ideal for exploring the city's attractions, like the Du Hang Pagoda or the Hai Phong Opera House, and enjoying outdoor activities without the interruption of heavy downpours. The drier weather also makes day trips to nearby Cat Ba Island and Ha Long Bay much more enjoyable, as you'll have clear skies for boat tours and sightseeing.The shoulder months of October, November, March, and April are particularly good as they avoid the peak tourist crowds and the hottest temperatures of summer.
