What is the weather in Halong Bay in Vietnam by month?

The weather in Halong Bay is divided into two main seasons: dry cool winter and humid hot summer. The best months to visit are considered April-May and September-October, when the temperature is comfortable, precipitation is low, and the sky is most often clear.

Winter months (December-February) are the coldest and driest, but the temperature can drop to 10°C, and sometimes lower. During this time, there can be piercing winds, making staying on the water not the most pleasant. In summer (June-September) it is very hot, heavy rains occur, and storms are possible, which can spoil the impression of the trip.

Here is a brief overview of the weather by month:

• December-February: Cold and dry, temperature 10-20°C.
• March: Warming begins, but the water is still cool.
• April-May: Ideal for visiting — warm and few rains.
• June-September: Hot, humid, possible downpours and storms.
• October-November: Comfortable weather, but the beach season ends.

When planning a trip, consider that on rainy days visibility worsens, and you may not see the famous landscapes in all their glory.
