Congo is a tropical nation, which means it has a tropical climate. The wet season lasts from March to June and the dry season for the rest of the year. Temperature and humidity are high as in all tropical nations. The rivers of the country are flooded seasonally.

The terrain is a variation of coastal plains, mountainous regions, plateaus and fertile valleys. About 70 percent of the country's area is covered by rain forest. The highest point, at 1,020 m, is Mont Nabeba in the Mayumbe mountains. The major rivers are the Congo River at the border with the Democratic Republic of the Congo, and the Kouilou-Niari River.

A 2014 expedition leaving from Itanga village discovered a peat bog "as big as England" which stretches into neighboring Democratic Republic of Congo.

UNESCO has declared two world biosphere reserves in the country: Odzala in 1977 and Dimonika in 1988.

Natural resources include petroleum, timber, potash, lead, zinc, uranium, copper, phosphates, gold, magnesium, natural gas, and hydropower.

As of a 2012 estimate, 1.55% of the land is arable, while only 0.20% contains permanent crops. Approximately 20 km² is irrigated (2003 estimation).

Environmental issues include the high level of air pollution from vehicle emissions, water pollution from the dumping of raw sewage, tap water not being potable, and deforestation.

Congo is party to the international agreements on Biodiversity, Climate Change, Desertification, Endangered Species, Ozone Layer Protection, Tropical Timber 83, Tropical Timber 94, Wetlands. It has signed but not ratified the Law of the Sea and so on.
