  • Median
  • Min./Max.
  • Measured

The line shows the median of the FOEN model forecasts at each timestamp; the band shows their minimum and maximum. Daily cards average the available hourly medians, which is not a daily median. A wider band means greater spread between model paths, not guaranteed upper or lower limits. Partial days may contain fewer forecast values.

How to read the chart: the thick line is the current year, the thin one the median of the 1991-2020 reference period. The shaded band shows the normal range (25th–75th percentile), the dotted lines the maximum and minimum. Values above the band are unusually high for the season, below unusually low – but not an official warning.

Understanding the water level

What is the water level of Lake Lugano? See the latest available level, its measurement time and source. Compare readings from the same station to understand the trend.

Reading in context

Putting Lake Lugano's current level in context

The main station at Melide reports a water level of 270.43 m a.s.l. at Sep 22, 2026, 3:50 AM. The series is provided by Bundesamt für Umwelt (BAFU). This value is the elevation of the water surface above the official height datum, not the water depth at the shore.

The median for the same calendar day is 270.47 m a.s.l.; the current value is 4 cm below it. The 270.38–270.52 m a.s.l. band contains the middle 50 percent of reference values from 1991-2020. Being outside it is less usual, but is not in itself a hazard level.

Comparison with the nearest valid readings gives 0 cm over 24 hours and -3 cm over seven days. These are net changes between two points in time; they prove neither a continuous rise or fall nor its cause.

Understanding Lake Lugano

Lake Lugano (Lago di Lugano, Lago Ceresio) lies in Ticino and extends into Italy. The Melide gauge sits on the causeway between the lake's two basins.

This overview includes 11 monitoring stations for water level, discharge, and water temperature. Not every station provides every measurement. Track changes at the same station, checking the timestamp, unit and source notes.

The curve shows recent level changes. A seasonal median, where available, compares the same time of year. Water can rise while remaining below that median: trend and comparison answer different questions. Neither replaces an official warning.

Measurement quality and sources

Data status

  • Measured — Recorded directly at a monitoring station.
  • Modelled — Computed by a scientific model (e.g. lake temperature from Alplakes), not measured on site.
  • Calculated — Derived from existing measurements, e.g. a balance or a change.
  • Archive image — Last archived image, not live.
