Geography

Hégenheim is a small town located in the northeastern quarter of France and in the southeastern part of the Haut-Rhin department.

Hégenheim is part of the french suburb of Basel and is adjacent to the swiss town of Allschwil.

Climate

Hégenheim features a moderately continental climate but nevertheless under maritime influence do to its significant exposure to prevailing winds and low-pressure areas from western France.

The town faces the Belfort Gap and thus is not protected by any mountain range which generates (on average) a higher amount of annual precipitation than in the rest of Alsace.

On the other hand, this precipitation falls mainly at the end of spring and in the summer when the dew point is high and thunderstorms numerous.

The village's weather station has the particularity of being a little higher up, in a place regularly exposed to wind and near many trees. These factors keep average maximum temperatures cool in all seasons despite the low altitude of the weather station.

Winters are cold and drier with weakly positive average maximum temperatures, around 4 °C to 6 °C. Snow falls each winter in a weak to moderate manner although long episodes of heavy snow have already been recorded, sometimes out of the winter season.
