Seal pup season in the UK depends on the species and colony. Common, or harbour, seals usually give birth in June and July. Grey seals pup later, mostly from September to December, with some colonies continuing into winter. Always watch from a distance, keep dogs away, and never approach a lone pup, as its mother may be nearby. Use local Wildlife Trust or National Trust guidance for colony-specific access rules.
