Average temperature across Nigeria in September.
Sahel & Semi‑arid north - Maiduguri, Sokoto, Katsina
By late September the rains taper in many Sahelian zones, leaving fields green and dusty tracks drying out; daytime temperatures creep back up into the low 30s°C but nights become more comfortable. This transition period is useful for overland travel because most flood risks recede while landscapes are at their most verdant. Expect mosquitoes to remain common and carry repellent when visiting lowland ponds and seasonal lakes.
Kano, Kaduna, Zaria
Rainfall gradually wanes in September, leaving cooler, fresher air and drying tracks; daytime highs rise slightly but mornings remain comfortable in the mid‑20s°C. This window is good for visiting cultural festivals and archaeological sites as wet‑season colors remain but flood risks reduce. Expect muddy footpaths around rural attractions and keep waterproofs handy for late afternoon showers.
Jos, Plateau State, Abuja approaches
September’s rains taper gradually and the plateau transitions to a drier, greener phase; afternoons clear more often and trails become less treacherous. Waterfalls remain strong but the risk of flash flooding declines, making this a fine time for longer hikes and photography. Night temperatures remain cooler than the lowlands - bring a light jacket for early starts on ridge walks.
Lagos, Ibadan, Akure
September sees the rains gradually easing toward the end of the month, with more frequent dry intervals and lush, green landscapes across the Lagos‑Ibadan corridor. Travel becomes easier as flooding risks decline, and evening sea breezes return to make alfresco dining pleasant again. The foliage is at its peak and photography of coastal mangroves and estuaries is rewarding after the long rains.
Port Harcourt, Warri, Calabar, the Delta creeks
September sees the rains slowly lessen by month’s end but the landscape stays sodden and rivers remain high; the oppressive humidity begins to ease a little toward October. This is a quieter travel time with fewer tourists and abundant bird and life sightings in reserves such as the Cross River National Park, though muddy trails persist. Pack good waterproofs and allow extra time for all intercity connections.
There are no major festivals or events in Nigeria during September to be aware of.
