When is the best time to travel to Hanoi and nearby Halong Bay for your trip? We're here to answer that question…
The Best Times to Visit Hanoi (and nearby Halong Bay)
For great weather...
Weather-wise, the best times to visit Hanoi and nearby Halong Bay are February to April and October to November.
February to April marks the time of spring, with warm and sunny days, comfortable temperatures, and plenty of flowers in bloom. Average daily high temperatures rise from 20°C to 28°C (68–82°F) during spring.
From October to November, the city experiences its sunny and drier fall season. During this time, the weather is mild and pleasant, with lower humidity and average high temperatures decreasing from 29–25°C (84–77°F).
For fewer crowds and lower prices...
If you want to avoid crowds and get lower prices, the best time to visit Hanoi is during the low season, which runs from May to September. During this time, you will find fewer tourists, cheaper accommodations, and more deals. However, it's worth noting that this period coincides with the hot, humid, rainy season, which means you may experience frequent showers and storms.
For high season...
If you prefer to visit Hanoi during the high season, which runs from October to February, you will experience cooler and drier weather. However, you can expect higher prices for accommodation, tours, flights, and larger crowds at popular tourist attractions.
The peak season coincides with holidays and festivals, such as the Lunar New Year (Tet) and Christmas, so you may also need to book your accommodation and tours well in advance. Contact us to plan your trip early.

Bangkok and Chiang Mai
In Bangkok, our guide Ann and driver "Mr. Ot" (I don't know how to spell his name) were very friendly and professional. You simply can't underestimate the value of having an English speaking guide to show you around, and a driver with a comfortable, sizeable, air-conditioned van take you from place to place. Ann taught us so much about Thailand's history, food, and religion. Mr. Ot always opened our door with a smile, and had cool towels and ice-cold bottled water for us. More

Excellent guide in Siem Reap
Our recent time spent in Siem Reap was made even more memorable by our expert guide, Som Piseth. Som was knowledgeable, attentive, flexible and super helpful - we learnt so much about Siem Reap and Cambodia in our 3 days with him. His English was excellent and his knowledge of, and pride in, his country was outstanding. We would highly recommend Som for anyone wanting an excellent guide in Siem Reap! More

The Worst Times to Visit Hanoi (and nearby Halong Bay)
With regards to weather, the worst time to visit Hanoi and Halong Bay is during the summer months from May to September.
During these months, the weather is usually hot and humid, with daily high temperatures averaging around 35–38°C (95–100°F) and high levels of rainfall. Additionally, there is a high chance of typhoons (with the highest risk period being from August to September) and heavy rains.
During the typhoon season, your Halong Bay cruise may be canceled and the visibility can be poor due to the mist and fog that often covers the bay during this time. Contact us for alternative recommendations.
On the bright side, at those times you can find the most favorable prices and enjoy less-crowded attractions. The heat can also be avoided as much as possible by organizing your schedule wisely. Although rain is a bit of a nuisance, it usually rains in the late afternoon or early evening. So, it wouldn't affect your whole visit.
