Hanoi experiences a subtropical climate with distinct seasonal variations in temperature but remarkably consistent humidity levels throughout the year. The city enjoys an unusually dry climate pattern with no recorded rainfall across all months, making it quite different from typical Southeast Asian monsoon patterns. The year divides into a cool, dry period from December through March with comfortable temperatures ranging from the high 60s to low 70s°F, followed by a hot period from May through September where temperatures peak in the low 90s°F. The consistent 70% humidity level year-round creates a moderately humid atmosphere that visitors should prepare for regardless of season. The temperature progression is very predictable, with the coolest months being December through February, a pleasant spring warming period in March and April, peak heat from June through July, and a gradual cooling from August through November. This dry climate pattern makes Hanoi an excellent year-round destination, though the extreme heat of summer months may be challenging for some visitors. The lack of a distinct rainy season means outdoor activities and sightseeing can be planned with confidence throughout the year.
