If you don’t want to get wet, avoid Southern Benin’s rainy seasons in April to mid-July, and mid-September to late October. Northern Benin gets a soaking from June to early October. The hottest time of the year is from February to April when temperatures can soar to 46°C in the north (the coastal south is significantly cooler). Harmattan winds billow out of the Sahara between December and March, so November and February are your windows of opportunity for a pleasant stay.
Parts of the northern Atakora region occasionally receive heavy rainfall, and smaller roads throughout Benin may be impassable during the rainy seasons; notably those in the wildlife parks, particularly Parc Regional du W.
