The heavy downpour in Ibadan, Nigeria that devastated the ancient city on August 26 has been described by the International Institute of Tropical Agriculture (IITA) as the highest in more than five decades.

It observed that the rainfall on that day hit an all-time high of 187.50 mm accompanied by wind gusts reaching 65 kilometers per hour. The previous highest recorded rainfall was 178.30 mm in September 1987.

IITA said that the August 26 rains started at 16:40H and continued until 20:00H, with intermittent drizzling until 23:00H. Rainfall was most intense between 18:10H and19:20H when 75% of the rain fell.

It noted that the more than six-hour rain led to flooding, toppled trees and damaged crops in many experimental plots in IITA. The extent of damage, although much at IITA and its neighboring communities was however, reduced as the IITA dam served as a buffer and a water ‘collection reservoir’ thereby reducing the amount of water flowing out to the creeks in neighboring communities.

According to it, elsewhere in Ibadan, the rainfall destroyed many lives and property, damaged key infrastructure such as bridges and roads, and pulled down electric poles. IITA’s weather data showed that the average daily rainfall in August 2010 was 8.9 mm considering all days, and 25mm considering only the rainy days. Maximum daily rainfall for August 2010 was 62 mm.
