Natural factors

The geological substrate is structured by Paleogene and Cretaceous limestone platforms, dating from 23 to 130 million years ago.
The uniformity of the soil derives from a layer of wind-deposited silt (loess) that can exceed one metre in depth, covering and penetrating the limestone formations across all the plateaus of Île-de-France.
The relief is gentle, with a mean elevation of around 100 m, ranging from the high points of Haravilliers at 218 m and Mont Pagnotte at 221 m down to the low points of Port-Villez at 11 m and the Paris City Hall at 33 m.
The climate is cool oceanic in type, with a very slight continental influence toward the east, receiving an average of 680 mm of annual rainfall, of which 330 mm falls between April and September.
The mean Huglin heliothermal index for Île-de-France is 1,760, placing the geographical area in the cold climatic zone for viticulture.
The hydrographic network is fairly dense, with watercourses flowing mainly from east to west — including the Seine, the Marne, the Oise, and the Eure — which have deeply incised the geological strata and created a large number of slopes exposed predominantly to the south and north.
