Where to Go in Nigeria in May
Far North
Sahel & Semi‑arid north - Maiduguri, Sokoto, Katsina
By early May the first convective storms sometimes appear on the horizon, but much of the Far North remains largely dry while the heat intensifies to its annual peak. Afternoons are punishing and the landscape looks parched, though occasional thunderheads may bring dramatic but localized downpours that turn dirt tracks to mud. If you’re trekking or using rural transport, plan flexibly: sudden showers can delay travel despite not yet being the full rainy season.
Northern Savanna & Sahel Transition
Kano, Kaduna, Zaria
By May thunderstorms begin to appear more often on the horizon, though many areas still only see sporadic rain - when it does come it’s intense and short‑lived. Afternoon storms can disrupt regional flights to Kano and produce sudden flooding in poorly drained sections of Kaduna. This month is a transitional period: the countryside starts to green, but roads can be unpredictable after downpours.
Middle Belt & Jos Plateau
Jos, Plateau State, Abuja approaches
May increases rainfall and turns the Plateau lush; by now routes to Bukuru and Barkin Ladi can have saturated berms and trickling streams. Scenic drives to spots like Assop Falls are more dramatic, but some rural roads become difficult without a high‑clearance vehicle. Mosquitoes increase and evenings grow more humid, so lightweight long sleeves and repellant are advisable for market evenings and night photography.
Southwest & Lagos Coast
Lagos, Ibadan, Akure
May ushers in the full rainy season for the southwest with frequent, often heavy afternoon and evening thunderstorms that cool the day but turn roads slick; Lagos experiences its wettest period across May-June. Urban flooding in low‑lying neighborhoods is common after prolonged storms, which can slow ride‑hailing and local ferries. Travelers should focus activities on mornings and book accommodation away from flood‑prone streets.
Niger Delta & Southeast
Port Harcourt, Warri, Calabar, the Delta creeks
May is the start of the true peak rainy season: relentless humidity, heavy downpours and high river levels are typical - the creeks swell and boat rides are a dramatic, but wetter, affair. Flooding is common on low‑lying roads around Warri and Burutu, and some ferry crossings run on altered schedules. Travelers should prioritize sturdy, waterproof footwear, insect protection, and flexible itineraries for nature excursions.
Events & Festivals in May
