Benin's climate is hot and humid. Annual rainfall in the coastal area averages 1,360 mm (53.5 in), not particularly high for coastal West Africa.
According to the 2002 census, 27.1 percent of the population of Benin is Roman Catholic, 24.4 percent Muslim (mainly Sunni), 17.3 percent Vodun, 5 percent Celestial Christian, 3.2 percent Methodist, 7.5 percent other Christian denominations, 6 percent other African Traditional Religion groups, 1.9 percent other religious groups, and 6.5 percent claim no religious affiliation.
As with many African countries, the Benin culture constitutes a number of different tribes. Naturally, wedding customs in Benin and traditional marriage practices will and do vary from tribe to tribe and culture to culture. Both monogamous as well as polygamous marriages are seen in the Benin culture but the traditional wedding is pretty much the same regardless.
