The climatic conditions of the Delta present two types since 
in winter those of the Mediterranean province extend over the whole 
of it, while in summer the Saharan type predominates except in a 
comparatively narrow belt near the coast. Observations are not 
numerous and Alexandria and Port Said on the north, and Cairo 
on the south furnish the only series of any length. The passage 
from the moister conditions of the cultivated area to the aridity of 
the desert is shown by Ismailia and Suez on the east and a short 
series from Wady Natrum on the west.
