Key Summary- Togo is dominated by a tropical savanna climate (Aw), with a small pocket of hot semi-arid climate (BSh) in the far north.
- A surprisingly dry coastal belt along the Gulf of Guinea contrasts sharply with the wetter, cocoa-growing highlands just inland.
- The harmattan wind from the Sahara shapes the dry season, delivering dust-laden air that can cut visibility and bring cooler morning temperatures.
Togo’s narrow shape, stretching from the Gulf of Guinea to the Sahelian fringe, creates a compact but varied climate tapestry. We base this guide on WeatherBox’s Köppen climate classification map, which shows tropical savanna (Aw) covering most of the country. In the extreme northern savannas around Dapaong, conditions transition toward a hot semi-arid (BSh) zone, where annual rainfall dips and the dry season extends longer. Geography plays a decisive role. The cold Guinea Current and winds blowing parallel to the coast suppress rainfall, making Lomé unusually dry for its latitude, while the interior Togo Mountains force moisture-laden air upward, feeding lush vegetation. The seasonal rhythm is set by the migration of the Intertropical Convergence Zone, which brings rains in two main waves across the south and a single burst across the north, followed by months of dust and dryness as the harmattan dominates.
Regional differences are striking and shape everyday conditions. The dry coastal belt around Lomé sees two uneven rainy spells: a heavier one from April to July and a shorter, less predictable one from September to October. Humidity stays stubbornly high, even when rainfall is scant, and the harmattan haze often filters the sun from November to February. Inland, around Kpalimé and the Togo Mountains, orographic lift wrings out far more moisture, sustaining the vividly green landscapes of coffee and cocoa country. This area can receive well over 1,500 millimetres of rain annually, often delivered in intense afternoon downpours. To the north, the climate shifts to a single rainy season that typically runs from May to October, with July and August bringing torrential rain and stickily hot conditions. The harmattan then ushers in a long, dusty dry period when daytime temperatures routinely climb above 35°C (95°F) but nights can feel surprisingly fresh. Wildlife gather at shrinking waterholes, making Kéran National Park’s game viewing especially rewarding late in the dry season. Lomé’s beaches and the colourful Grand Marché remain accessible year-round, though the dust-laden harmattan skies can mute coastal panoramas.
For most travellers, the optimal window falls roughly between November and March. During these months the harmattan tames humidity, rainfall is low, and temperatures are warm but rarely punishing, although sensitive visitors should prepare for dusty air. April and October serve as shoulder months with sporadic storms that can briefly disrupt road travel in rural areas. The wettest weeks, particularly in June and September, can turn unpaved northern routes into muddy challenges and limit the appeal of hiking the lush highland trails around Mount Agou. Packing for Togo means lightweight, breathable cotton clothing, sturdy sun protection including a wide-brimmed hat, and a dust mask if you are bothered by airborne particles. A compact raincoat remains useful from April through October. We encourage you to browse WeatherBox’s climate charts and monthly temperature ranges to pinpoint the best moments for spotting birds in the wetlands or enjoying the dazzling dry-season light along the coast.
