Aare, Thun (outflow) – Water level
This station shows Water level at the outlet of Lake Thun. It describes the outlet area and does not automatically represent the lake level or temperature.
Current level
547.98m a.s.l.→
Measurement time:
Current FOEN data are unchecked raw data and may be corrected later. A recent measurement time does not mean that a value has been validated. FOEN data quality
Current context
Largely stable over the last 24 hours.
What does this change mean?
“Largely stable” means the change from the comparison value about 24 hours earlier is less than 2 cm. The chart shows fluctuations in between.
We compare values at the same station at two points in time. If no suitably timed comparison value exists, we omit that statement. An unchanged value does not mean a seasonal normal or an all-clear. Changes below the displayed precision are also described as stable.
Past 30 days at a glance
NormalMedian of available daily means: 548.17 m a.s.l. · 30 days in the comparison window.
The current individual value is compared with available daily means from the last 30 complete days, using Coordinated Universal Time (UTC) for day boundaries. Min. and max. refer to daily means, not individual peaks. A day counts when values exist; gaps can affect its mean. For model series, this compares model values. “High” refers to this short window, not an official danger level or a seasonal normal.

Over the past 24 hours the value ranged between 547.98 m a.s.l. and 547.98 m a.s.l. and stayed largely stable.
Based on 139 available values from Oct 3, 2026, 3:20 AM to Oct 4, 2026, 3:20 AM (Swiss local time). The range describes stored values, not necessarily every peak that occurred.
The forecast value is expected to fall by about 28 cm across the 5 displayed forecast days.
Forecast
Source: FOEN forecast- 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.
Understanding readings at Aare, Thun (outflow)
A level in metres above sea level describes the surface elevation in the stated datum, not water depth. Use the same station for trends. Networks or countries may use different vertical datums, so a numerical difference does not necessarily represent a physical height difference.
Check the time and source first, then the chart and unit. Missing or disrupted readings cannot support a reliable current assessment. A short comparison describes recent changes, not flood probability. Follow official warnings and local instructions for safety decisions.
