The step guage became operational on 15 July 2010. The gauge is situated on the outer breakwater by kind permission of Port Isaac Harbour Commissioners. The shore station is kindly hosted by Port Isaac Aquarium. Images of the tide gauge can be found at: http://www.channelcoast.org/gallery/grid/equipment/oceanographic_instruments/stepgauge/.
The primary purpose of the step gauge at Port Isaac is as a tide gauge, but the instrument also measures waves. Some wave reflection from the sea wall is to be expected, but a reasonable estimation of wave height is anticipated.
