מזג האוויר בקאן טהו במרץ

December to March is the dry season here and March is its hot end - regulars say the south turns properly hot from March through May, and travellers report days that felt like 39C. Our row says exactly that: 34.7C reading as 39C, with nights that only fall to 25.6C and rain almost absent at 19.4mm across 3.3 days. Humidity at 67 percent is low for this city, which is the season's one mercy. The practical advice is cotton, shade in the middle of the day and something with sleeves against the sun rather than the cold, since there are 11.1 hours of it. The record: a dew point of 21.9C, a 14.3 kph wind and AQI 64.

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.
