The geological subsoil consists of sandstone and limestone and is covered by loess layers of different thickness.

The Elz river created alluvial gravel and sand sediments that had been used as pastures but were adapted for agriculture in many cases.

The climate in this area is close to a Mediterranean microclimate, and there is adequate rainfall year-round.

However, more year-round rain occurs than in the Rhine plateau because of the closeness to the Black Forest.

However, it is close to being humid subtropical (Cfa) due to the mean temperatures in July and August just under 22 °C.
