Weather in Qui Nhon in March
Vietnam · 20-year averages, March
Prime time. If you get to pick your dates, March is the one. The heat itself is manageable at 26.8 °C, but 83% humidity is what you will actually feel.
March ranks 2 of 12 in Qui Nhon. Only February scores clearly higher, and the difference is small enough to be settled by price rather than weather.
Rain falls on only 5 days, so an itinerary with no wet-weather fallback is a reasonable risk. Natural fibres and a second shirt for the day. At 83% nothing dries, including you.
What the averages hide
Averages flatten a month, and this one hides a few things: it never really gets hot: not one day in an average March reaches 30 °C; the day barely swings — 2.4 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest March day reached 29.6 °C and the coldest night fell to 19.9 °C, and the wettest single day dropped 73 mm — roughly 228% of the month's rain in one day.
This is the volatile part. March rainfall has ranged from 3 mm to 103 mm across the twenty years measured — a 100 mm spread around an average of 32 mm. The average is real but almost no individual March looks like it, so treat the figure as the middle of a wide range rather than a forecast.
Wind is light at 13.3 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 83%, high enough to notice on the warm days without dominating them.
How March sits in the year
Temperatures hold steady either side: 25.3 °C in February, 26.8 here, 28.7 in April. Nothing about the timing within the month matters much.
Daylight in March
Qui Nhon sits close enough to the equator that daylight barely moves all year — 12 hours in March, against a range of just 1.6 hours across the whole calendar. Sunrise and sunset land at roughly the same time whenever you come.
Sea temperature
The sea sits at about 26.1 °C in March — warm enough to stay in as long as you like. The sea peaks at 29.5 °C in June and bottoms out at 25 °C — water lags the air by a month or two, which is why the best swimming often comes after the best weather.
How busy it gets
Busy. Popular without being frantic; book the things you care about, improvise the rest.
Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.
March in Qui Nhon versus nearby
If Qui Nhon is one option among several, the nearby comparison is worth making. Nha Trang is close enough to be a coin toss — within a degree on temperature, the same number of rain days. Hoi An is the weaker option in March — within a degree on temperature, 2 days more rain.
So: March works, with February the better month by 7 points if the dates can move. If they cannot, nothing here should stop you booking.
