Sägistalsee is a lake in canton of Bern, Switzerland. Its surface area is 7 ha (17 acres). The lake's sediments were studied to determine past climate and human activities. Since the site is located in a closed, 46 m deep depression, a pronounced Cold-air pool forms when meteorological conditions are right. A privately operated automatic weather station has been recording the air temperature at the current location by the lake since October 30, 2022. Since then, temperatures below −40 °C (−40 °F) have been measured twice, including a low of −42.4 °C (−44.3 °F) in January 2023. This is the lowest temperature recorded in Switzerland in the winter of 2022–23.[1][2] MeteoSwiss has described the Sägistalsee reading as plausible, but emphasises that it was obtained by an amateur station in a very small cold-air hollow and therefore reflects highly local microclimatic conditions; it does not replace the official Swiss low-temperature record of −41.8 °C (−43.2 °F), measured at La Brévine (Neuchâtel) on 12 January 1987 by the national observing network.[3][4][5]
