Seasons

Hanoi has two main seasons, the northeast monsoon months of November to April and the southwest monsoon months of May to October. The northeast monsoon season can be further divided into a winter season from November to February, which sees the coolest and driest days with average temperatures of 10-15°C and only 20mm of rain. Springtime runs from February to April, when warmer temperatures are accompanied by more rain, up to 80mm in April. The southwest monsoon summer months of May to September can get uncomfortably hot (temperatures into the mid-30s) and humid with heavy rains, especially in July and August when each month gets an average 320mm of rain. The autumn months of September to November are generally sunny and mild.
