When to go, by what you want to see
The delta has two seasons, but our trips follow four calendars: the flower growers before Tet, the fruit orchards in summer, clear dry-season mornings for boats and cameras, and the flood season when boat yards are busiest. This page sets them side by side.

The weeks before Tet: flowers
Tet, the Lunar New Year, falls on 6 February in 2027 and 26 January in 2028. In the four to five weeks before it, the Sa Dec flower village is at its fullest, with growers bringing on Tet plants on raised beds above the canals. Cai Mon, the second plant centre, follows the same rhythm, with buds set in the second half of the twelfth lunar month.
Visitors from Ho Chi Minh City arrive in numbers at the weekends. Some private gardens in Sa Dec close from the 23rd to the 25th of the twelfth lunar month, a about a week before Tet, and visitors seldom come during Tet itself. Many family workshops also stop for the first days of the new year. We plan weekdays in early to late January for 2027.

December to April: dry mornings
The dry season is the time the national tourism authority recommends, and the time our trips run most smoothly. Rain is rare, mornings are clear, and sun-dried crafts such as rice paper and puffed rice cakes are made every day. December and January are Can Tho’s coolest months; April is the hottest, with mean daytime highs near 34 °C, which pushes sessions earlier.

May to August: fruit, with rain
The rainy season begins in May, and Can Tho records rain on about 16 to 22 days a month through the summer. In exchange, the orchards are at their heaviest from May to August — rambutan, durian, longan, mangosteen, mango — and the delta is at its greenest. The flower village is quieter; plants are sold all year, but not at Tet scale.
Dengue peaks in southern Vietnam from June to October. Bring repellent and cover up at dusk.

September to November: high water
September is Can Tho’s wettest month. The flood season peaks upriver from September to November, and in October and November riverside streets in Can Tho and Vinh Long can flood at the highest tides. It is also when the wooden-boat yards near Sa Dec are busiest, as orders come in for the flood.
For photographers, the season brings heavy skies and high water; for everyone, it brings the risk of a lost morning. We add a spare half-day to trips in these months where we can.

Heat, rain and what to pack
The delta is warm in every month. In Can Tho, mean daytime highs run from about 30 °C in December and January to about 34 °C in April, and humidity stays high all year, highest in the wet season. Pack light, loose clothes that cover shoulders and knees for temples and old houses, a hat, and sandals that can get wet stepping in and out of boats.
From May to November add a light rain layer and mosquito repellent for dawn and dusk sessions; in Can Tho it rains on most days from June to October. On boats in the early morning a thin long-sleeved layer is welcome even in the dry season, and life jackets are carried on every boat we use.

Common questions
Questions travellers ask most
What is the single most rewarding month?
It depends on the trip. For Sa Dec, January before Tet. For photography and crafts, December to March.
Is the rainy season a bad time?
No, only a different one. Expect some wet mornings, but the orchards are full and the delta is at its greenest.
What happens at Tet itself?
Families celebrate, many workshops stop, and the flowers have been sold. We avoid planning sessions in the first days of Tet.
When is Tet in 2028?
26 January 2028, so the flower weeks fall in late December and January.
