Lake
Embalse Lanuza Sallent De Gállego
Embalse Lanuza Sallent De Gállego water temperature is currently Cold. Cold water ahead. Cold shock is a real risk on entry. Limit your time in. Located in the Alpine climate zone, it is currently spring. A smoothed air average of 8°C over recent weeks means the lake surface is firmly cold. Wetsuit strongly recommended. Cold shock is a real risk on entry.

Solar heating at altitude is not modelled. Estimates are not reliable above 1200m.
Lake size
Larger lakes warm and cool slowly. Ponds respond quickly to air temperature.

Frequently asked questions
How is the lake water temperature estimated?
Lake temperature is estimated using exponential smoothing of 60 days of air temperature data, based on Kettle et al. (2004). The algorithm accounts for lake thermal mass. Larger lakes respond more slowly to air temperature changes. This is not a direct measurement; accuracy is approximately plus or minus 2 to 3 degrees C.
What do the temperature categories mean?
Each category covers a 4 degree C band: Warm (20 degrees C or above, no wetsuit needed), Comfortable (16 to 20 degrees C, most swimmers fine), Cool (12 to 16 degrees C, wetsuit optional), Cold (8 to 12 degrees C, wetsuit recommended), Very Cold (4 to 8 degrees C, wetsuit essential), Ice Risk (below 4 degrees C, experienced swimmers only).
What is the geographic zone?
The zone is derived from the lake's latitude and altitude. It reflects the climate regime: temperate zones have the highest model accuracy; alpine and equatorial highland zones have reduced accuracy due to solar heating effects not fully captured by air temperature data alone.
What is the swimmer exit temperature?
The exit temperature uses the Steadman (1984) apparent temperature formula, which accounts for wind speed and humidity on wet skin. Exiting water in wind with wet skin causes significantly faster heat loss than the air temperature alone suggests, especially at speeds above 20 km/h.
