refreshing – perfect for a swim
As of: Mon 28 Sep 2026, 14:00
Lake Attersee is the largest lake lying entirely within Austria – deep, clear and, because of its size, a little slower to warm up than Mondsee or Wolfgangsee. The gauge is in Unterach at the southern end, easy to reach from St. Gilgen via Mondsee.

Data source: Hydrographic Service of the State of Salzburg, salzburg.gv.at/wasser/hydro. The values are measured automatically at the lake gauges and fetched here every 15 minutes; “as of” is the time of the last reading. No guarantee – before swimming, test with your toe.
