Where to Go in West Africa in August
Senegal & The Gambia
Dakar, Saint‑Louis, Casamance & Banjul
August continues the wet, humid pattern across Casamance and the southern Gambia, with frequent intense rains, leaching heat, and a real risk of localized flooding; travel times increase and airlines sometimes adjust schedules. Dakar and the northern coast often see fine spells between squalls and are still reasonable for sightseeing. Prepare for insect‑heavy evenings, bring repellents and durable waterproof footwear for walking in village areas.
Upper Guinea / Monsoon Coast
Guinea‑Bissau, Guinea, Sierra Leone & Liberia
August continues with high rainfall and very humid conditions; Conakry and Freetown see sustained storms and often grey, low clouds. Roads into the Fouta Djallon and Loma ranges are particularly vulnerable to washouts; local markets and fishing activity are affected by heavy surf. Take anti‑mosquito precautions seriously and allow extra travel time - domestic flights can be delayed more than usual.
Gulf of Guinea
Côte d’Ivoire, Ghana, Togo & Benin
August often remains wet, and in some years the Gulf of Guinea experiences two rainy maxima that extend through this month - expect persistent cloud, warm air and regular storms. Cotonou and Lomé will be humid with afternoon squalls and occasional street flooding. Cultural sites and forest treks are still doable but require waterproof gear and contingency plans for transport delays.
Nigeria
Coastal south, Lagos, Niger Delta & Jos Plateau
August keeps intense, regular rains in the south and central belt - Lagos and Delta provinces remain wet and sticky; this is a low season for tourism. City infrastructure can be strained, so allow extra time for commutes and transfers. Mosquito numbers peak; bring strong repellents and consider accommodation with screened windows or air conditioning.
August remains squarely in the rainy season with frequent storms, thick skies and high humidity in the southern Sahel band - agricultural landscapes are lush but travel times lengthen significantly. Markets and seasonal villages are active with harvest work, but many tourist facilities operate at reduced capacity. Prioritize travel on main roads and expect limited rural services.
