Last Update June 4, 2020

Esanland is influenced by two yearly seasonal winds. These are the South — West and the North — East winds. The former blows from the Atlantic Ocean from April to October, and is warm and humid. The wind prevails over the land and brings in its wake heavy rains. The period is symbolized with much human activity when the planting of various crops including yams by the farmers and their families was done. When rainfall stops by mid-October period of dry season sets in to bring the North East winds. This usually lasted from November to March when there is virtually no ram in Esanland. The Esan climate at this time is very hot with a temperature of about 23° — 25 centigrade at midday. From December to January’ the weather becomes so harsh that it is referred to as the harmattan or okhuakua. According to Akinbode these seasonal variations in the region could be due to the ‘latitudinal migration of the inter — tropical convergence zone (ITCZ).Although rainfall is unevenly spread throughout the period of the rainy season, light rainfalls are at times recorded in the months of December and January. Again strong winds and high air temperatures could be recorded between the months of January and March while the lowest are recorded during the months of June and July. Generally, the altitude of the Esan plateau modified the temperature to such a level of eliminating extreme weather conditions. It is therefore not surprising that the relatively flat tops of the plateau are much cooler than parts of the land throughout the year.
