Weather in Cần Thơ in March

A hard month. March is a hard month in Cần Thơ, and worth planning around. Daytime highs average 36.7 °C and the afternoon is not negotiable — outdoor plans move to early morning or evening.

March ranks 4 of 12 in Cần Thơ: past the worst of the year but short of January, which is the month to book if the dates are open.

Rain falls on only 4 days, so an itinerary with no wet-weather fallback is a reasonable risk. Pack for heat management rather than style: shade, water, and a schedule that gives up on the middle of the day.

What the averages hide

Averages flatten a month, and this one hides a few things: 25 days of the month clear 35 °C — that is not a heatwave, it is the month. Across the twenty years measured, the hottest March day reached 41.2 °C and the coldest night fell to 19.5 °C, and the wettest single day dropped 25 mm — roughly 119% of the month's rain in one day.

This is the volatile part. March rainfall has ranged from 0 mm to 70 mm across the twenty years measured — a 70 mm spread around an average of 21 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 11.3 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 63%.

How March sits in the year

Temperatures hold steady either side: 34.9 °C in February, 36.7 here, 36.9 in April. Nothing about the timing within the month matters much.

Daylight in March

Cần Thơ sits close enough to the equator that daylight barely moves all year — 12.1 hours in March, against a range of just 1.2 hours across the whole calendar. Sunrise and sunset land at roughly the same time whenever you come.

An inland climate

Despite being inland, the year stays fairly even: 15.2 °C between the year's warmest afternoons and coldest nights.

How busy it gets

Quiet. Few other visitors, cheaper rooms, and a real chance some seasonal operators are shut.

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

March in Cần Thơ versus nearby

If Cần Thơ is one option among several, the nearby comparison is worth making. Ho Chi Minh City is the weaker option in March — within a degree on temperature, 2 days less rain. Vũng Tàu is a better bet in March — 2.7 °C cooler, 1 day less rain.

So: March is a compromise. January is 25 points better and is what Cần Thơ is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
