Generally the best time to see them is at the start of the summer in late May/June. Some years we will see hundreds all through the summer and into the autumn e.g. 2006 and 2007, some years there will be an intense flurry of activity over one period e.g. 2010 and some years there will be very few all year e.g. 2011! If you are really interested in basking sharks and want to maximise your chance of seeing them then the best thing to do is follow our Sightings page. Once we start to see them regularly then email or call and book your trip.
