Lomé, the capital of Togo, sits on the Gulf of Guinea coast of West Africa, on a low sandy strip between the Atlantic and a lagoon at approximately 6.14°N, 1.22°E. It has a tropical savanna climate (Köppen Aw) — hot and humid year-round, cooled by sea breezes — with the double rainy season characteristic of the Guinea coast, and it is notably dry for its latitude.

There is no summer in the temperate sense: temperatures stay warm and steady, with daytime highs around 30–32°C and warm, humid nights, tempered by the ocean breeze. The main rainy season runs from around April to July, when the heaviest rain falls, with June typically the wettest month, though downpours are shorter and lighter than further west along the coast.

There is no true winter, but the main dry season from November to March is warm and sunnier, with lower humidity and little rain. The Harmattan, a dry, dusty wind off the Sahara, reaches the coast between December and February, hazing the sky and briefly drying the air. A shorter second wet spell comes around September and October.

Lomé is surprisingly dry for the Guinea coast, receiving only around 800–900 mm of rain a year — far less than Abidjan or Lagos — in a double-peaked pattern, with a main rainy season from April to July and a weaker one in September and October. Live rainfall, humidity, and pressure readings for the city are shown in the panels above.

Lomé sits within a curious dry anomaly along the Guinea coast: the coastline here runs roughly parallel to the moist monsoon winds rather than across them, so the air is not forced upward to release its rain, leaving Togo and neighbouring Ghana's coast markedly drier than the drenched coasts to the east and west.
