Da Nang Weather by Month

Da Nang sits at 16°N latitude in Central Vietnam, where the climate is governed by two distinct seasonal patterns: a dry season produced by the southwest monsoon (February–August) and a wet season driven by the northeast monsoon (September–November). The swing between the two is dramatic — October's 620mm of monthly rainfall versus March's 22mm represents a 28x difference in precipitation volume.

The data below is drawn from Vietnam National Hydrometeorological Administration (VNMHA) long-term averages. All figures represent typical conditions; individual years vary. Use this guide to set realistic expectations, not to guarantee specific weather on your travel dates.

January is Da Nang at its quietest. The northeast monsoon is winding down, leaving residual cloud cover, occasional short rain bursts, and sea conditions too choppy for comfortable swimming. The beach infrastructure is open, but red flags appear regularly.

The city infrastructure operates fully: restaurants, museums, and cultural sites run normally. Marble Mountains and the Ba Na Hills cable car remain accessible. January is a legitimate option for those combining Da Nang with Hoi An and Hue — just don't base the trip around beach time.

February marks the beginning of Da Nang's genuine dry season. Rainfall drops from January's 66mm to around 28mm, spread across fewer and shorter events. The sea continues to improve — not yet fully calm, but noticeably better than January.

Tet (Lunar New Year) falls in late January or early February. It brings Da Nang's most spectacular annual event — fireworks nightly, street festivals, and the city's most atmospheric week. Restaurants partially close for several days around the actual Tet date.

March is statistically Da Nang's driest month and, for most visitors, its best. The 22mm monthly average reflects a genuine low-rainfall window where days of unbroken sunshine are the norm rather than the exception.

Hotel rates are still at shoulder-season pricing — typically 20–30% below the July–August peak. Beachfront properties are available without weeks of advance booking. The beach conditions are as good as they get: calm water, clear skies, comfortable 28°C temperatures.

April is the month that most experienced Da Nang visitors cite when asked for a recommendation. The 30°C average high is warm enough to justify beach time in earnest but hasn't yet reached the oppressive heat of July–August.

The Da Nang International Fireworks Festival typically begins in late April — international teams compete with choreographed displays over the Han River on weekend evenings, drawing large crowds to the riverside. If you want to attend, book accommodation well ahead of competition dates.

May extends the dry season into warmer territory. The 32°C average high is the point at which midday beach activity becomes genuinely intense — the combination of direct sun and rising humidity makes early morning or late afternoon the best beach times.

Rainfall ticks up to 55mm from April's 35mm, but showers remain brief and typically fall in the late afternoon. Sea temperature reaches 28°C — at its most comfortable for extended swimming. The Fireworks Festival may extend into May.

June marks the transition from pleasant dry season to full Vietnamese summer. School holidays bring significant domestic tourism volumes — families from Hanoi and Ho Chi Minh City arrive at Da Nang's beach hotels, and My Khe becomes visibly busier.

Rainfall increases to 82mm, concentrated in afternoon and evening showers that rarely last more than an hour. The Dragon Boat Festival falls in June on the lunar calendar, bringing racing on the Han River. Book 6–8 weeks ahead for July–August dates from this point.

July is the month when Da Nang's beach infrastructure runs at maximum. The sea is at its warmest — 30°C sea temperature means you can stay in for hours without discomfort — and sky conditions are consistently clear.

Rainfall at 76mm is slightly lower than June, distributed across brief afternoon storms that typically clear within an hour. Lightning strikes during these storms are taken seriously — beach red flags during electrical storms are mandatory. Hotels are at their fullest; rates are at their highest.

August broadly continues July's conditions — hot, humid, beach in excellent shape — but with two notable changes. Rainfall increases to 100mm as the transition toward the monsoon begins. Typhoon risk is real but historically lower than September–November.

Most years August passes without direct typhoon impact. Some years bring significant tropical storm systems that close beaches for several days. Travel insurance with weather coverage is worth taking out for August trips. Peak season rates remain in effect.

September is where Da Nang's climate makes its most dramatic turn. Rainfall jumps from August's 100mm to 280mm — nearly three times the volume — driven by the northeast monsoon establishing itself over Central Vietnam.

Beach swimming becomes unreliable. Red flags appear frequently. The city's food and cultural infrastructure operates normally — Da Nang's restaurant scene, museums, and landmarks are all accessible. Hotel rates begin to drop from peak levels: 20–30% reductions are common.

October is Da Nang's most challenging month without qualification. The 620mm average monthly rainfall is not a figure to contextualise — it represents more precipitation in 31 days than London receives in an entire year.

Hoi An, 30 minutes south and a common day trip from Da Nang, experiences severe flooding in October that can make the historic old town inaccessible for days at a time. If a Da Nang–Hoi An itinerary includes October, check historical flood records before booking non-refundable accommodation. Hotel rates drop 40–50% from peak.

November is a month of gradual transitions. Rainfall falls from October's extreme 620mm to a still-significant 380mm — an improvement in relative terms that doesn't translate to a reliable visitor experience in the first half of the month.

The second half of November is meaningfully better. By mid-month in most years, storm frequency has reduced and clearer windows between weather events are longer. Temperatures at 25°C are comfortable for city exploration. Some years produce swimmable beach days in late November; others don't.

December is Da Nang without the beach — and for the right visitor, that's still a worthwhile proposition. The monsoon has cleared, leaving a cooler (23°C), occasionally overcast city with 125mm of monthly rainfall.

What works in December: the city's food and cultural scene operates fully. The MICHELIN-recognised restaurant strip, the Han Market, and Da Nang's growing café culture are at their best when the heat is off. Hoi An is 35 minutes south and works well in December when the flood risk has passed.
