Port Isaac


Additional Information

 Step gauge location  50° 35.651' N  004° 50.065' W
 Storm threshold  2.3 m



Wave and tide data are measured using an Etrometa step gauge which 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:

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.

A power cut last night has stopped data transmission. Ongoing power issues will be resolved asap.
