Sara and John say...
Make no mistake - this is a hot tropical country.
However - from the arid lands of the north to the rain-forests of the south - the climate is varied across Nigeria.
Across northernmost areas, much of the year is dry. The winter months see low humidity; and although the days are very warm and sunny - approaching 40 Celsius as spring arrives - the nights can get quite chilly. Rainfall is mostly confined to the summer months, with the wet weather focussed mainly in July and August.
But don’t assume it’s raining all the time. The downpours mostly occur in the afternoon. Showers linger into early autumn, before dry and sunny weather returns to end the year.
Further south, the wet season lasts progressively longer. And although the summer temperatures don’t peak to the extremes found further north, don’t be fooled. The higher humidity and cloud cover make southern areas much stickier, especially during the long wet summer months. In fact at the capital, Abuja, the highest daytime temperatures are found in winter - peaking in the high 30s Celsius - when most sunshine occurs.
Along the coast the temperature and rainfall is more evenly spread through the year, although winter remains the driest period.
So, for visiting Nigeria, we’d recommend the winter months, especially December and January.
