NAME

Tidalwater - Tidal water information

DESCRIPTION

Water level forecast for a specific harbors in Norway. Weather condition adjustments are generally available for the immediate three days.

Water level have two components: Tidal forces (TIDE) and the influence of weather (SURGE). Tidal forces is the basis for calculating waterlevel. Forecast of weather conditions for the specified harbor is then used to adjust this basis (TOTAL). Waves are not included in the forecast, only long period phenomena.

Values are given as centimeters above mean sea level. See https://kartverket.no/sehavniva/data-pa-se-havniva/viktige-vannstandsniva/ for further information on the reference water level.
