Sea surface temperature is measured by the station network covering the coast and the islands.
Measurements are performed by non-professional (where possible, at main meteorological stations by professional) observers
according to the MHS Marine Meteorological Department guidelines.
Observation logs are forwarded by mail at the end of each month. Data are entered into the computer, checked and stored.
At certain locations a sea temperature sensor has been added to automatic system to continually measure sea temperature.
