During this period, divers can encounter seals, basking sharks, dolphins, and vibrant underwater ecosystems. Spring and summer months typically offer calmer seas and longer daylight hours, ideal for exploring coastal sites and wrecks. Autumn can also provide excellent diving conditions with fewer crowds and rich biodiversity. Winter diving is possible but more suited to experienced divers due to colder waters, rougher seas, and reduced visibility.
