Halong Bay is at its best when you travel from March to May!

March till May is definitely the best time to travel to Halong Bay in terms of weather. Spring is ending and summer is starting; the weather is relatively cool with the best chances of sunshine.

The alternative?

From June to August, there are lots of typhoons occurring- and no one wants to enjoy their vacation with a raincoat or an umbrella, right? And between August and November, the weather may be even worse.

Drizzling, cold wind, cloudy skies and mists prevent you from enjoying the terrific view of Halong Bay.

According to the Tourist Season

Vietnamese people usually take their vacation in summer, so at that time of year Halong receives a lot of domestic visitors.

On the weekends, the tourist wharf can be pretty chaotic. Hotel rooms always run out of vacancy, and the famous tourism hotspots turn into makeshift shopping malls.

In the high season price inflation is a huge problem that faces foreign visitors. You are often asked for extra money for goods and services if you are a foreigner, no matter where you came from.

Could you imagine one 500ml bottle of water during peak time may cost you about 3 USD? It’s insane. However, travelling to Halong during the off-peak season (March represents the start of the off-peak season) is a different story.

There will be plenty of available rooms and places won’t be too crowded. Moreover, the price of beverages, services, and everything else is acceptable.

What’s the bottom line?

The good weather from March to May coincides with the changeover between peak/off-peak season, arguably making it the best time to visit Halong Bay.

Best Time to Visit Halong Bay on a Cruise

Cruising is the most popular way to explore the bay, but it’s a weather dependent activity- so time of year matters.

What’s the best time to visit Halong Bay on a cruise?

We already know that March to May offers the best weather in terms of temperature, sunlight, and rainfall- but let’s look at the other months to get a more well-rounded view.

From August to November, the chance of the bay being hit by a monsoon increases dramatically, which poses a risk to cruises planning to go out into the water. If a storm is on the way, cruises tend to cancel their operations.

December to February is great weather-wise, the temperature drops down to the late teens and rain is pretty infrequent. However, this is considered to be peak-season, so prices hike and the crowds roll in.
