the north. It has a surface area of . The Höri, (about 45-square-kilometres) also extends towards the Island of Reichenau, and separates the Zeller See to the north from the Rheinsee to the south. In the southeast, near the mouth of the new Rhine Canal, the Rohrspitz juts out about into the lake and forms the western perimeter of the Bay of Fußach. It has an area of about 50 hectares. The Wasserburg peninsula has a castle, Schloss Wasserburg, and the parish church of St. George. The peninsula is on the northeastern shore of the Obersee between the Bay of Nonnenhorn in the west and Bay of Wasserburg in the east. It has an area of and was an island until 1720, when the Fuggers built a causeway. In March 2009, 27 people lived on the peninsula. The Galgeninsel ("Gallows Island") in the Bay of Reutin is also a peninsula that was formerly an island. It is only 0.16 hectares in area. Shore The shores of Lake Constance consist mainly of gravel. In some places there are also sandy beaches, such as the Rohrspitz in the Austrian section of the lake, the Langenargen and Marienschlucht. According to the data of the International Water Protection Commission for the Lake Constance, the approximate shore length is (see Coastline paradox). The inflow of water is constantly changing, mainly due to rain and the snow melt in the Alps. Its average surface area is about (in Switzerland the absolute value is slightly higher in m above sea level). The more or less regular seasonal fluctuations in the water level also lead to slight variations in shore length and differences in the shore zone habitats (depending on high and low water).

It has a subtropical microclimate, which allows
