The peak season of Halong Bay is from December to January. These periods mark Halong Bay’s highest number of tourists, thanks to its ideal weather and various things to do.

From the beginning of December, Halong’s beauty is at its best, with clear skies and calm waters that make it ideal for cruising and kayaking on the bay. The temperature is pretty decent, ranging from 20–25 °C (68–77 °F) to 17–20 °C (63–68 °F) with very little rainfall. Visit Halong Bay during peak season, which also opens great chances for you to join many cultural events such as New Year’s, Christmas, or the Halong Bay Festival.

Another option: Shoulder Season

 

If you hate the crowd but still want to enjoy Halong to the fullest, shoulder season might be an alternative time for you. The shoulder season in Halong Bay starts from February to April.

The shoulder season starts with a chilly temperature in February (~15°C) and gets warmer toward the end of April (~25°C). This is also the spring season, and the blooming of flora and fauna in the area will coat Halong Bay with a fresh green color.

However, you could expect quite a bit of rain during this season, especially during February (with an average of 12 days of rain per month). The rain is not heavy, but it tends to be cats and dogs for a few days. Besides, Tet Lunar New Year (the most important holiday in Vietnam) tends to fall in this month, which might cause the price to go higher, sometime even doubled.

The cheapest time to visit Halong Bay is the low season, from May to September. Cruise operators or hotels tend to have special discounted rates during these months, and you could save at least 10–20% compared to other seasons.

Of course, it’s cheap for a reason. The weather might get quite extreme sometimes, especially during July and August, when a lot of storms come to the bay. The typhoon tends to last for 2–3 days and might seriously affect your travel plans, especially if you have your cruise booked by that time. It’s also the hottest month of the year, with an average temperature of 28°C that might even go up to 32 ~ 33°C plus a high level of humidity.

However, if you are a little careful in your planning, traveling to Halong Bay from May to September could be a decent trip with a good budget. Try to keep track of the forecast, especially within 5-7 days prior to the departure, which could help you make a better plan and avoid any travel disruption. A small extra tip is to make sure all your bookings have special conditions during extreme weather, like a typhoon, so that you can easily amend or avoid charges when you can’t travel.
