Da Nang's Climate
Tucked between the Hai Van–Ba Na mountain arc to the north and west and the open sweep of Da Nang Bay to the east, Da Nang enjoys one of the most forgiving climates on Vietnam's central coast. The Bach Ma range and Hai Van Pass blunt the worst of the northeast monsoon, so winters here are noticeably milder than just across the pass: January, the coolest month, still averages nighttime lows around 19.9°C — warm enough for a midday beach stroll. The trade-off is rain: about 2,308 mm a year, most of it crammed into the final months.
The sunny half: My Khe at its best
From roughly February to August the city settles into its signature weather — dry, sunny and calm. June is the hottest month, with average highs of 34.1°C, and occasional dry westerly winds can make mid-afternoons feel fierce, with very high UV. This is prime season on every front: My Khe, Non Nuoc and Xuan Thieu beaches turn glassy and clear, the Son Tra peninsula is at its greenest for rides up to Linh Ung Pagoda, the fishing fleet at Tho Quang works its main season, and Nam O village sun-dries anchovies for its famous fish sauce. Late in the dry season the city quietly worries about fresh water, as the Cau Do River — its main supply — often turns brackish when the upstream Vu Gia catchment runs low.
The wet season: downpours and typhoons
The rains run from September through January, when the northeast monsoon collides with tropical convergence zones just offshore. October is the deluge month: 628 mm on average across 28 rainy days, meaning barely a dry day all month. It is also peak typhoon season — intense cloudbursts have flooded low-lying streets like Me Suot in Lien Chieu and the alleys of Thanh Khe, while the Cu De and Tuy Loan rivers out in Hoa Vang can rise fast. Rough seas keep boats in harbour, but the winter swell turns My Khe into the city's surfing spot.
Ba Na Hills: the city's rooftop
Less than 30 km from downtown, the Ba Na summit at nearly 1,500 m stays cool year-round, typically 7–8°C below the city, with sunny mornings dissolving into afternoon fog. Pack a light jacket whatever the month, even in June.
Planning tips
For swimming and hikes on Son Tra or the Marble Mountains, aim for March–August with serious sun protection in June–July. From September to December, check storm bulletins before booking and keep coastal plans flexible. December–February is mild and breezy at around 20–24°C — ideal for riverside cycling along the Han and open-air seafood dinners with nothing heavier than a windbreaker.
