Quick Summary: Can Tho weather follows the Mekong Delta’s dry season (December–April) and wet season (May–November) pattern, with the best time to visit being December to February for the clearest mornings at the Cai Rang floating market. April is the warmest month at 28.9°C, while January is the coolest at 25.9°C.
As the unofficial capital of the Mekong Delta, Can Tho’s weather is inseparable from its rivers — the Hau River and its web of smaller canals shape both the humidity in the air and the rhythm of daily life, from the floating markets at dawn to the afternoon rain that follows almost like clockwork in the wet season.
Can Tho Weather at a Glance
- Can Tho weather peaks in April at 28.9°C and dips to its coolest in January at 25.9°C.
- Dry season runs December–April, with rain days as low as 3 in February and March.

- The delta logs around 222 rain days a year — among the wettest of Vietnam’s southern towns, reflecting its river-heavy geography.
Best Time to Visit
December to February is Can Tho’s most comfortable stretch: rain days drop to 3–6 a month, temperatures sit around 25.9–26.7°C, and mornings on the water at Cai Rang floating market are calm and clear. This period also avoids the seasonal river flooding that can affect low-lying areas later in the year.
Weather by Seasons
Dry Season (December–April): Temperatures climb from 25.9°C in January to 28.9°C by April, with rain days rising from 3 to 11 as the season winds down. Waterways run lower and clearer, which is good news for boat trips through the canals.
Wet Season (May–November): Average temperatures ease to 26.5–28.4°C, but rain days jump sharply, from 21 in November up to 29 in July. As Climate-Zone.com’s Can Tho climate records note, this is also when the Mekong’s seasonal flood pulse — locally called mua nuoc noi — can raise water levels in low-lying parts of the delta from around August through November.
Daily Weather & Humidity Insights
With rivers and canals on every side, Can Tho’s air stays humid even in the driest months — typically 65–75% in the dry season, climbing toward the mid-to-high 80s during the wet season’s heaviest rain. The day-night temperature gap is usually a moderate 6–8°C, a little narrower than drier inland provinces since all that surface water holds heat overnight. Early mornings on the water can feel refreshingly cool before the sun climbs.
What to Wear and Pack
- Lightweight, quick-dry clothing suited to humid river air.
- A light rain jacket or poncho, especially May through October.
- Closed, non-slip shoes for boat docks and market walkways that can get wet or muddy.
- A wide-brimmed hat and sunscreen for open-air boat rides.
- Insect repellent for evenings near the canals.
Essential Local Tips
- Visit Cai Rang floating market at first light (around 5–6am) — both the light and the boat traffic are best before mid-morning.
- From roughly August to November, check local water-level reports before planning trips to low-lying riverside areas, as seasonal flooding can affect access.
- Dry-season mornings (December–February) give the clearest reflections on the canals for photos. See more things to do in our our full Can Tho travel guide.
