In the month of July Pakistan received below normal monsoon rains; however in August and September the country received above normal monsoon rains. A strong weather pattern entered the areas of Sindh from the Indian states of Rajasthan and Gujarat in August and gained strength with the passage of time and caused heavy downpours. The four weeks of continuous rain have created an unprecedented flood situation in Sindh.[4][5][6]

The District Badin in Sindh province received record breaking rainfall of 615.3 millimeters (24.22 in) during the monsoon spell breaking earlier recorded 121 millimeters (4.8 in) in Badin in 1936.

Qamar uz Zaman Chaudhry, Director General Pakistan Meteorological Department said: "the rains in Sindh are the highest ever recorded monsoon rains during the four weeks period of August and September, 2011. Before the start of these rains in the second week of August, Sindh was under severe drought conditions and it had not received any rainfall for the last 12 months. The last severe rainfall flooding in Sindh occurred in July 2003," he said and added, "but this time the devastating rains of Mithi, Mirpurkhas, Diplo, Parker, Nawabshah, Badin, Chhor, Padidan, and Hyderabad etc during the four weeks period have created unprecedented flood situation in Sindh."
