The visibility must be recorded during every Shorewatch because it affects the probability of a sighting. For this reason Shorewatch is not carried out in ‘bad’ visibility of less than 1 km*.
On a clear day when the visibility is excellent you will be able to see greater distances, increasing the chance of spotting a cetacean during your watch and vice-versa in bad visibility. Visibility is assessed based on how far you can see in relation to places and distances. Each location will have its own WDC Shorewatch Visibility Key which outlines appropriate distances and local landmarks.
Using your eyes only assess the visibility based on the specific locations in your site’s visibility key. Record your final assessment of the visibility using the appropriate code in your key, from 1 (Bad) to 6 (Excellent). Mark this in the visibility column on your data sheet before beginning your 10-minute Shorewatch.
