Climate Oceanic with temperate summers, average annual rainfall reaching 590 mm, and average minimum and maximum temperatures of 1 °C and 8 °C in February (coldest month), and 13 °C and 25 °C in August (hottest month).
Soil The soils have generally good potential on the plateau, with a reserve for temporary hydromorphic zones; quite poor on the Perche sand and on slopes. They are of a brown earth type leached throughout the massif with a silty-clay texture and are quite deep on flint clays (1 to 2 m deep) and are shallow to superficial on slopes and outcrops of Perche sands.
Geology The geological layer is made up of Upper Cretaceous formations represented, over most of the territory, by sedimentary flint clays (eastern part) and Perche sands that outcrop on the slopes to the west and north of the massif.
