Current water temperature
6.0°C↓
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
Down 0.8 °C over the last 24 hours. 0.5 °C higher than 7 days ago.
What does this change mean?
“Largely stable” means the change from about 24 hours earlier is less than 0.3 °C. There may still have been a warmer afternoon or a cooler night.
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
Very lowMedian of available daily means: 7.3 °C · 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.

Understanding readings at Rosegbach, Pontresina
The temperature applies to the stated location and time. A sensor in a tributary does not represent the beach or other depths. Temperature alone says nothing about current, water quality or bathing safety.
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.
