This article describes the geography of Guinea-Bissau.
The climate in Guinea-Bissau is tropical. This means it is generally hot and humid. It has a monsoonal-type rainy season (June to November) with southwesterly winds and a dry season (December to May) with northeasterly harmattan winds.
Guinea-Bissau is warm all year around and there is little temperature fluctuation; it averages 26.3 °C (79.3 °F). The average rainfall for Bissau is 2,024 millimetres (79.7 in) although this is almost entirely accounted for during the rainy season which falls between June and September/October. From December through April, the country experiences drought.
Terrain and ecology
The terrain of Guinea-Bissau is mostly low coastal plain with swamps of Guinean mangroves rising to Guinean forest-savanna mosaic in the east.
The lowest point on Guinea-Bissau is at sea level at the Atlantic Ocean. The highest point on Guinea-Bissau is 300 metres above sea level at an unnamed location in the northeast corner of the country.
Natural resources found in Guinea-Bissau include fish, timber, phosphates, bauxite, clay, granite, limestone and unexploited deposits of petroleum. 8.31% of the land is arable and 250 square kilometres is irrigated. Natural hazards include a hot, dry, dusty harmattan haze that may reduce visibility during the dry season and brush fires. Severe environmental issues include deforestation; soil erosion; overgrazing and overfishing.
Near the Senegal border there have been historic sightings of the Painted Hunting Dog, Lycaon pictus, but that endangered canid may now be extirpated in that locale.
