For the period 1991-2020, the average annual temperature observed at the nearest weather station, located in the commune of Saint-André-de-Sangonis, 3 km away as the crow flies,[4] is 15.5 °C (60 °F) and the average annual total rainfall is 652.4 mm.[5][6] For the future, climate parameters for the municipality estimated for 2050 according to different greenhouse gas emission scenarios can be consulted on a dedicated website published by Météo-France in November 2022.^{[Map 1]}

The commune's land use, as revealed by the European biophysical land cover database Corine Land Cover (CLC), is characterised by the importance of agricultural land (96.9% in 2018), an increase compared to 1990 (77%). The detailed breakdown in 2018 is as follows: permanent crops (56.5%), heterogeneous agricultural areas (40.4%), forests (3%).[7] Changes in land use in the municipality and its infrastructure can be seen on various maps of the area: the Cassini map (eighteenth century), the carte d'état-major (1820-1866) and IGN maps or aerial photos for the current period (1950 to the present).
