Southern Vietnam: HCMC, the Mekong Delta, and the Islands

Southern Vietnam is the country's commercial and demographic centre — about 35 million people, the largest city, the most agricultural exports. The geography is largely flat: river delta, low coastal plain, and offshore islands.

The geography

• The South-East — HCMC and the surrounding provinces (Bình Dương, Đồng Nai, Bà Rịa-Vũng Tàu). Highly industrialised; site of most foreign-owned factories.
• The Mekong Delta — 12 provinces, fed by the nine mouths of the Mekong. The country's rice bowl and the world's largest pangasius fish-farming region.
• The southern coast and islands — Vũng Tàu (weekend beach), Côn Đảo (former prison island, now eco-tourism), Phú Quốc (the big tropical island).

The climate

The south has only two seasons:

• Dry season (Nov–April) — hot, sunny, low humidity. The peak tourist season.
• Wet season (May–October) — daily afternoon downpours, high humidity, lush landscapes.

It's warm year-round — HCMC ranges roughly 25–35°C, never cold.

The cities

• Ho Chi Minh City — the largest city, commercial centre, more cosmopolitan than Hanoi.
• Cần Thơ — the largest Mekong delta city.
• Mỹ Tho — small delta city, gateway to Mekong tours from HCMC.
• Vũng Tàu — beach city, weekend escape from HCMC.
• Phú Quốc — large island in the Gulf of Thailand.

The food

Southern cuisine is the country's most exuberant — sweeter, more coconut, more tropical fruit. Cơm tấm, bánh xèo, hủ tiếu, cá kho tộ, bún mắm. Cantonese influence is heavy in HCMC's Chợ Lớn district. Coffee comes with sweetened condensed milk by default.

What's distinct about the south

• The Saigon accent is softer, slower, and merges two of the tones — five tones in practice.
• The largest Catholic population.
• More French-era loanwords and a noticeable French legacy in old Saigon architecture.
• Higher percentage of ethnic-Chinese population (Chợ Lớn, HCMC).
• Vietnam's largest ethnic-Khmer population (Trà Vinh, Sóc Trăng).
• Faster-paced, more commercial, more international-facing than Hanoi.
