Traveller notes on Can Tho in September
Other months in Can Tho
Vietnam forum regulars generally rate the Mekong Delta, Can Tho included, as one of the less rain-disrupted regions to visit in August compared to the beach coasts - hot and humid, yes, but the typical pattern is a squally, thunderstorm-heavy shower for an hour or two in the afternoon rather than an all-day washout. Several posters specifically recommended a slower pace, like an overnight homestay, to work around the weather rather than rushing between sights. It's still the wet season, so pack for rain daily, just don't expect it to ruin the day.
Forum posters consistently name February as one of the best months for southern Vietnam generally, including the Mekong Delta region around Can Tho - warm, dry and noticeably less humid than the wetter months later in the year. Posters recommend the area specifically for a floating-market day trip, noting Can Tho draws far fewer tourists than the well-trodden north-south circuit despite being a worthwhile stop. The broader southern-Vietnam framing from posters is straightforward: this is the region's dry season, and February sits comfortably within it, making it a reliable window for delta boat trips and outdoor sightseeing.
