Geography

Overview

Cà Mau is the southernmost province of Vietnam, in the Mekong Delta. The mainland part of the province is located at 8034' to 9033' north latitude and 104043' to 105025 east longitude, 370km from Hồ Chí Minh City, 180km south of Cần Thơ.

Cà Mau is located on a peninsula, has a rather special geographical location, with 3 sides adjacent to the sea. Cà Mau Cape is the only place on land where you can watch the sun rise from the South China Sea in the morning and set in the Gulf of Thailand in the afternoon.

Terrain

Ca Mau is on a delta region, with rivers and canals. The average height is 0.5 meters to 1.5 meters above sea level. The direction of the terrain is gradually inclined from North to South, from Northeast to Southwest.

The area of Cà Mau is in the lowlands with flooding especially in the southern edge. It has five main soil groups: acid sulfate soil, peat soil, alluvial soil, saline soil, and canal soil.

The local low-lying areas in the central low-lying area of the Cà Mau Peninsula have a topographic relationship with the ancient riverbed. The lowlands of U Minh and Trần Văn Thời are inland "hanging depressions" limited by the natural dikes of the system of Ông Đốc, Cái Tàu, Trẹm rivers and high ledges along the West Sea (Gulf of Thailand). This hanging low-lying area stagnates water all year round and becomes a swamp. Most of the land in Cà Mau is a younger land formed by sedimentation, accumulated over the years, somewhat fertile and suitable for aquaculture, rice cultivation, mangrove planting, brackish flooding, etc.

Cà Mau has ecosystem of forests in coastline (which streches up to 310 kilometers) and inland where it covered 35.000 hectares of land. 77% of mangrove forests in Mekong region is located in Cà Mau.

Climate

Cà Mau is featured for its near-equatorial Tropical monsoon climate (Khí hậu nhiệt đới gió mùa cận xích đạo). It has 165 days in a year containing rain with 2.360 mm annually. The average annual humidity is 85.6% and the average annual temperature is 26.5°C. The highest average temperature of the year occurs in April, around 27.6°C. The lowest average temperature is in January, which is about 25°C. The average annual temperature range is 2.7°C.

Rivers and Hydrology

Cà Mau features a dense and interwoven network of rivers and canals, resembling a spiderweb, with a total length of approximately 14,000 kilometers of waterways. This extensive system provides favorable conditions for inland waterway transportation and logistics.

The river and canal system in Cà Mau is extensive and highly interconnected, featuring numerous large rivers with considerable depth that facilitate the transport of alluvium, contributing to the enrichment of the mainland. Major rivers in Cà Mau include the Tam Giang, Gành Hào, Bảy Háp, Sông Đốc, Đầm Dơi, Cái Tàu, Trầm Trẹm, Quản Lộ-Phụng Hiệp, and Bạc Liêu - Cà Mau rivers.

The tidal regime in Ca Mau is directly influenced by both diurnal and irregular semi-diurnal tides. The tidal range along the East Sea coast is relatively large, varying from 300 to 350 cm during spring tides and from 180 to 220 cm during neap tides.

History

Nguyễn dynasty

During the feudal era, the land of Cà Mau was mostly wild and uninhabited. According to Gia Định Thành Thông Chí by , under the reign of Emperor Gia Long, settlers had only begun to sparsely cultivate areas along rivers such as Ông Đốc, Gành Hào, and Bảy Háp. By the time of Emperor Tự Đức, the region was still primarily covered with mangrove forests, with fewer inhabitants due to the scarcity of fresh water and the acidic nature of the soil. In the 17th century, General Mạc Cửu, along with a group of Chinese immigrants, settled in Hà Tiên and later submitted the territory to the Nguyễn Lords. In 1808 (the 7th year of Gia Long's reign), this unit was renamed Long Xuyên District, under Hà Tiên Prefecture. By 1825 (the 6th year of Minh Mạng’s reign), the imperial court appointed a district governor to administer the area.

French colony

During the French colonial period, on June 15, 1867, the French established the Cà Mau administrative division (hạt) based on the former Long Xuyên District. On August 1, 1877, this division was dissolved and merged into the Rạch Giá division. In 1903, the Cà Mau administrative agency was established, consisting of three cantons: Quảng Long, Quảng Xuyên, and Long Thủy. On October 22, 1956, according to Decree No. 143/VN, Cà Mau Province was renamed An Xuyên Province, with its capital at . At the same time, An Xuyên Commune was renamed Tân Xuyên, which became the location of the provincial capital, Quản Long. At that point, An Xuyên Province consisted of six districts: Quản Long, Thới Bình, Sông Ông Đốc, Cái Nước, Đầm Dơi, and Năm Căn.

On March 10, 1976, the province of Cà Mau - Bạc Liêu was renamed Minh Hải Province, initially taking the provincial capital in Ca Mau. After 1975, implementing the Party and State's policies, the policy of building new economic regions was implemented in the Central Highlands, Mekong Delta, Southeast, with the purpose of exploiting and redistributing labor between regions and industries to increase social labor productivity. The new economic zone of Minh Hải province is also part of the policy of redistributing the labor force nationwide. From 1976 to 1985, a large number of residents of province volunteered to go to farms in Minh Hải province to reclaim land and start businesses. The land of “wild forest and weeds” gradually became a rich and developed land.Annually, the Central Government assigned Bạc Liêu - Cà Mau and Minh Hải provinces the target of mobilizing 120,000 - 180,000 tons of food. Minh Hải also needed over ten thousand tons of rice reserves to alleviate famine within the province. At that time, the central and ongoing task of the Minh Hải Provincial Party Committee was reclaiming land for summer-autumn rice cultivation, increasing crop yields, and carrying out the "three harvests" of food (collecting taxes, collecting debts, and purchasing). Provincial and district officials, even school staff, were mobilized to go to the grassroots level to work with the people in digging irrigation canals and carrying out the "three harvests" very regularly. Agencies and departments had to be self-sufficient in rice for 2-3 months each year. As a result, every agency sent people to farm for self-sufficiency.

In 1984, the provincial capital was moved to Cà Mau town, and the name Minh Hải town was reverted to Bạc Liêu town.

On April 14, 1999, Cà Mau town was upgraded to Cà Mau City. On November 17, 2003, Năm Căn District was re-established from Ngọc Hiển District, and Phú Tân District was re-established from Cái Nước District. Cà Mau Province consisted of one city and eight districts. On August 6, 2010, Cà Mau City was officially recognized as a grade-II urban center under the province.

In November 1997, the Cà Mau Peninsula was struck by Typhoon Linda (Openg). Thousands of people were killed, and an estimated 200,000 homes were destroyed, along with most of the Cà Mau fishing fleet.

Cà Mau Gas-Power-Fertilizer Complex is one of the three economic projects carried out in the Vietnam 2000-2005 period and along with the Cần Thơ Bridge it is "one of the two largest projects in the Mekong Delta".

On June 12, 2025, the National Assembly passed Resolution No. 202/2025/QH15, which took effect the same day, merging Bạc Liêu Province into Cà Mau Province and abolishing all district-level of Cà Mau Province.
