Hanoi in January One of the cooler months of the year. Winter is dry, but fog can sit over the mornings. In years when Tet falls in late January, streets get busy with preparations toward the end of the month and some shops begin to close.
Neither hot nor cold: 20°C by day and 15°C after dark. Spending hours on foot was easy. Showers came now and then, about 8 rain days in all, and most of the month stayed dry. It varied a lot from year to year. January 2021 had 2 rain days; 2024 had 20.
January 2025 averaged 22.6°C by day, 2.6°C above the 20-year mean. Mostly fine, light rain: about 5 mm per wet day, more mist than downpour.
