What is the average temperature in Da Nang?
The yearly average sits at roughly 26–27°C (79–81°F). Da Nang has a tropical monsoon climate on Vietnam's central coast, so the swing across the year is modest — there is no true cold season. The gap between the hottest and coolest months is only about 8–9°C in daytime highs, which is why the city feels consistently warm rather than seasonal in the way a temperate destination does. Figures on this page are long-term averages and vary from year to year.
Da Nang temperature by month (day & night)
The table below shows typical daytime highs, nighttime lows and sea temperature for each month, in Celsius and Fahrenheit. Use it to gauge how warm a given month runs, day and night.
| Month | Daytime high | Nighttime low | Sea temp. | Notes |
|---|
| January | ~25°C (77°F) | ~20°C (68°F) | ~24°C | Coolest stretch; wider day–night swing |
| February | ~26°C (79°F) | ~20°C (68°F) | ~23.5°C | Coolest sea; low humidity |
| March | ~28°C (82°F) | ~22°C (72°F) | ~24.5°C | Warming steadily |
| April | ~30°C (86°F) | ~24°C (75°F) | ~26°C | Warm, even days |
| May | ~31°C (88°F) | ~26°C (79°F) | ~28.5°C | Heat building |
| June | ~33°C (91°F) | ~27°C (81°F) | ~29.5°C | Among the hottest |
| July | ~34°C (93°F) | ~26°C (79°F) | ~29.5°C | Hottest daytime highs |
| August | ~33°C (91°F) | ~26°C (79°F) | ~29.5°C | Warm; sea at its warmest |
| September | ~31°C (88°F) | ~25°C (77°F) | ~29°C | Easing from the peak |
| October | ~29°C (84°F) | ~24°C (75°F) | ~28°C | Cooling down |
| November | ~27°C (81°F) | ~22°C (72°F) | ~26.5°C | Milder days |
| December | ~25°C (77°F) | ~20°C (68°F) | ~25°C | Coolest month; damp evenings |
Read down the columns and the shape of the year is clear: temperatures climb from February, peak across June, July and August, then ease back through autumn to a December–January low. Even at that low, daytime highs stay around 25°C, so a "cool" day in Da Nang is still shirt-sleeve warm.
Da Nang sea temperature by month
The sea stays swimmable year-round, ranging from about 23°C in February–March to around 29–30°C from June to September. Water temperature lags the air by a few weeks, so the ocean is at its warmest in late summer and its coolest in late winter — a little after the matching air-temperature extremes.
In practical terms, the water is warmest and most inviting across June to September, and coolest — though still mild by most standards — around February and March, when a longer swim can feel brisk. Sea temperature is a useful gauge the general air forecast usually leaves out, especially if swimming or watersports are a priority.
Hottest and coolest months
June and July are the hottest months, and December and January the coolest. The hottest daytime readings, around 33–34°C, land in June and July, while the mildest, near 25°C by day and 20°C at night, fall in December and January.
The day-to-night swing (diurnal range) is widest in the cool, dry months. In December through February, a warm 25–26°C afternoon can drop to 19–20°C after dark, a gap of five to six degrees, so evenings feel noticeably fresher. In peak summer the nights stay warm and the swing narrows, which is part of why July and August can feel heavy even after sunset.
How temperature varies by location around Da Nang
The same day can read several degrees apart across the area: the coast is mildest, the city centre runs warmest, and the hills at Ba Na are far cooler. Air temperature is not uniform, and the differences are large enough to plan around.
Along the beaches, a steady sea breeze keeps the air a degree or two below the downtown reading and makes late afternoons more comfortable. In the city centre, buildings and paving store heat, so central districts can sit roughly 1.5–2.5°C warmer than the coast, most noticeably at midday when road and pavement surfaces heat quickly. Up at Ba Na Hills, around 1,479 metres, the temperature typically falls 6–8°C below the city — cool enough that a light layer is worth carrying even in peak summer. If your plans mix beach, city and mountain in one trip, expect to feel all three of these bands in a single day.
Why Da Nang feels hotter than the thermometer
From May to August the "feels-like" temperature often runs several degrees above the actual reading, sometimes equivalent to 37–42°C. The cause is humidity: when the air holds a lot of moisture, sweat evaporates slowly, so the body cools less efficiently and the heat feels more intense than the number suggests.
Humidity is highest in the wetter, cooler months and the muggy edges of summer, and it also keeps warm nights feeling close. This is why a 34°C July afternoon in Da Nang can feel harsher than a 34°C day in a drier climate — the thermometer tells only half the story. Travellers from hot, dry regions often notice the difference most.

What to wear for each temperature band
Match your clothing to the temperature band rather than the calendar. The guide below turns the readings above into simple comfort choices.
| Temperature band | When it applies | What works |
|---|
| ~20–23°C (evenings) | Nights Dec–Feb | A light layer or long sleeves for after dark |
| ~24–27°C | Cool-month days; spring/autumn | Breathable cotton or linen; very comfortable |
| ~28–31°C | Mar–May and Sep–Nov days | Light fabrics, sun hat, sunglasses |
| ~32–34°C | Jun–Aug days | Loose, light clothing; strong sun protection; hydrate |
| Feels-like 37–42°C | Midday Jun–Aug | Avoid direct midday sun; seek shade and cooling breaks |
