Weather in Nha Trang in April

A good month. April is a solid month to be in Nha Trang. Highs average 29.1 °C, lows 26.8 °C, and rain falls on 8 days — nothing in the month is working against you.

April ranks 4 of 12 in Nha Trang: past the worst of the year but short of February, which is the month to book if the dates are open.

Rain on 8 days, 1 of them heavy. Enough to need a plan B, not enough to need a plan around it. Pack for 29.1 °C days and 26.8 °C nights; the spread matters more here than any single number.

What the averages hide

Averages flatten a month, and this one hides a few things: 4 days top 30 °C — hot spells arrive, but they break; the day barely swings — 2.3 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest April day reached 31 °C and the coldest night fell to 23.5 °C, and the wettest single day dropped 93 mm — roughly 211% of the month's rain in one day.

This is the volatile part. April rainfall has ranged from 2 mm to 174 mm across the twenty years measured — a 172 mm spread around an average of 44 mm. The average is real but almost no individual April looks like it, so treat the figure as the middle of a wide range rather than a forecast.

Wind is light at 12.8 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 80%, high enough to notice on the warm days without dominating them.

How April sits in the year

Temperatures hold steady either side: 27.4 °C in March, 29.1 here, 30 in May. Nothing about the timing within the month matters much. Rain is the thing that moves: May brings 12 days more of it, so the earlier half of a flexible trip is the safer half.

Daylight in April

Nha Trang sits close enough to the equator that daylight barely moves all year — 12.4 hours in April, against a range of just 1.4 hours across the whole calendar. Sunrise and sunset land at roughly the same time whenever you come.

Sea temperature

The sea sits at about 28.1 °C in April — warm enough that the water offers no relief from the heat. This is the warmest the water gets all year.

How busy it gets

Shoulder. The value months — prices ease off and you get the place closer to itself.

Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.

April in Nha Trang versus nearby

If Nha Trang is one option among several, the nearby comparison is worth making. Qui Nhon is close enough to be a coin toss — within a degree on temperature, 3 days less rain. Vũng Tàu is the weaker option in April — 5.4 °C warmer, 1 day less rain.

So: April works, with February the better month by 17 points if the dates can move. If they cannot, nothing here should stop you booking.
