You can expect average temperatures between 20°C and 25°C (68°F to 77°F). October and November are particularly lovely months with comfortable temperatures and fewer crowds compared to the peak season around Christmas and the New Year.

February, March, and April offer warm and sunny days, perfect for outdoor activities. The dry season provides the most comfortable conditions for enjoying all that Ha Long Bay has to offer, from the stunning views to the exciting activities.

The Wet Season: May to September

The wet season in Ha Long Bay brings higher humidity and more rainfall. This doesn't mean you should completely avoid visiting during this time, but it's important to be prepared. The rainfall is usually in the form of short, heavy showers, and the sun often comes out between the downpours. The average temperature during this period is around 28°C to 30°C (82°F to 86°F). May and June are transitional months, with a mix of sunshine and rain. July, August, and September are the wettest months, with the possibility of typhoons. However, even during the wet season, the bay is still incredibly beautiful, and you can often find sunny spells. The rain can actually enhance the scenery, making the limestone karsts look even more dramatic. Just be sure to pack rain gear, and be flexible with your plans. Cruises and other activities might be canceled or altered due to the weather. Also, the crowds are usually smaller during the wet season, so you can often find better deals on accommodations and tours.
