Climate and region of Hanoi
Hanoi is located in northern Vietnam, nestled within the Red River Delta. This region experiences a humid subtropical climate, sharing similar weather patterns with nearby destinations like Ninh Binh and Halong Bay. However, Sapa, situated further north at a higher altitude, has a cooler climate year-round despite being in the same region.
Hanoi’s climate features two main seasons: the dry season from November to April and the rainy season from May to October. Additionally, Hanoi experiences four distinct seasons—spring, summer, autumn, and winter. May marks the beginning of the rainy season, characterized by increasing temperatures, rising humidity, and occasional rain showers.
It’s important to note that Hanoi’s climate differs significantly from central and southern Vietnam. If you’re visiting Hanoi in May, expect warmer and more humid conditions compared to regions like Da Nang or Ho Chi Minh City, where the weather patterns vary due to their tropical and coastal influences.

Is Hanoi worth visiting in May?
May is a good time to visit Hanoi, especially if you enjoy warm weather and vibrant city life. The city is full of energy as it transitions into summer, with lush greenery and blooming flowers adding color to the streets and parks. While the rising temperatures and occasional rain showers mark the beginning of the rainy season, these brief showers often provide a refreshing break from the heat.
Hanoi, being a bustling urban destination, is less affected by weather fluctuations compared to nature-focused spots like beaches or mountainous areas. A sudden rain shower won’t significantly impact your ability to explore the city’s rich cultural landmarks, bustling markets, and vibrant street food scenes. Unlike beach destinations where rainy weather can limit activities, Hanoi offers an array of indoor attractions such as museums, art galleries, and historical sites that remain accessible regardless of the weather. This makes Hanoi a versatile and exciting destination to explore even during the start of the rainy season.
