The coastal areas have interconnected lakes and lagoons and elongated coastlines with wide marshes; part of Lake Nokoué lies within the department. The southern regions of Benin receive two seasons of rainfall from March to July and September to November, while the northern regions of the country receive one season of rainfall from May to September. The country receives an average annual rainfall of around 1,200 mm (47 in), but Atlantique Department receives less rainfall. The department has mostly low-lying sandy coastal plains towards the Atlantic Ocean, marshes, lagoons and lakes. The highest elevation in the department around the coastal plains is 20 m (66 ft), compared to the country's average of 200 m (660 ft) above mean sea level.
Freshwater and seawater fishing is the major profession in the region. Petroleum was discovered in the 1960s in offshore areas, while titanium, low quality iron ore, ilmenite and chromite are the major minerals.

Atlantique is subdivided into eight communes, each centered at one of the principal towns: Abomey-Calavi, Allada, Kpomassè, Ouidah, Sô-Ava, Toffo, Tori-Bossito and Zè. The department of Atlantique was bifurcated in 1999 when some of the Cotonou and the surrounding area were transferred to the newly formed Littoral Department.
Benin originally had six administrative regions (départements), which have now been bifurcated to make 12. Each of the deconcentrated administrative services (directions départementales) of the sectoral ministries takes care of two administrative regions. A law passed in 1999 transformed the sous-prefectures, the lowest level of territorial administration, into local governments. Municipalities and communal councils have elected representatives who manage the administration of the regions. The latest elections of the municipal and communal councils were held in June 2015.
