Question

During what five months of the year was the Nile river above flood level?

Answer 1

July through November.

"Compared with the flashy floods of the Tigris and the Euphrates, the historic Nile flood was much more benign, predictable, and timely. As is the case today, most of its flow originated from monsoon-type rains in the Ethiopian highlands. The remainder came from the upper watershed of the White Nile around Lake Victoria. With almost calendrical precision, the river began to rise in southern Egypt in early July, and it reached flood stage in the vicinity of Aswan by mid-August. The flood then surged northward, getting to the northern end of the valley about four to six week later.

At its peak, the flood would cover the entire floodplain to a depth of 1.5 meters. The waters would begin to recede in the south by early October, and by late November most of the valley was drained dry."
