Terrain and ecology

Guinea-Bissau's topography.

The terrain of Guinea-Bissau is mostly low coastal plain with swamps of Guinean mangroves rising to Guinean forest-savanna mosaic in the east.[1] A recent global remote sensing analysis suggested that there were 1,203km² of tidal flats in Guinea-Bissau, making it the 28th ranked country in terms of tidal flat area. [2]

The lowest point on Guinea-Bissau is at sea level at the Atlantic Ocean.[1] The highest point in Guinea-Bissau is Monte Torin with an elevation of 262 m (860 ft).[1]

Natural resources found in Guinea-Bissau include fish, timber, phosphates, bauxite, clay, granite, limestone and unexploited deposits of petroleum.[1] 10.67% of the land is arable and 235.6 square kilometres are irrigated.[1]

Natural hazards include a hot, dry, dusty harmattan haze that may reduce visibility during the dry season and brush fires.[1] Severe environmental issues include deforestation; soil erosion; overgrazing and overfishing.[1]

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.[3]

Climate

Further information: Climate change in Africa

Guinea-Bissau's climate 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.[1]

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 the capital city 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 receives very little rainfall.
