Overview
Grey Seals are the largest native land predator in Britain and a regular sight from Formby Beach. Pups are born on beaches and sandbanks in autumn — pure white at first, moulting to grey. They can haul out on the Ribble sandbanks and are often visible in the surf at Formby. Britain holds about 40% of the world population of Grey Seals, making the Sefton Coast sightings part of a genuinely important global story.

Frequently Asked Questions
Can I see Grey Seals from Formby Beach?
Yes. Grey Seals are regularly spotted from Formby Beach, particularly in autumn and winter. Scan offshore for heads in the surf, or look for hauled-out animals on the sandbanks visible at low tide. Keep a minimum distance of 50m from any seal on the beach — approaching seals causes stress and can cause them to abandon pups.
What should I do if I find a seal pup on Formby Beach?
Do not approach, touch or try to return it to the sea. Seal pups are often left alone by their mothers while she feeds — this is normal. Keep dogs on leads and people back. If the pup appears injured or distressed after 24 hours, call the BDMLR (British Divers Marine Life Rescue) on 01825 765546.
