Staff at Hunstanton Sea Life Sanctuary have cared for a record number of seals this summer.
The team has received 50 emergency calls and has treated a total of 37 seals since March.
Grey seals Artemus and Hemera, both found in March, will be the first to be released back into the wild at Snettisham tomorrow.
Artemus lost an eye following a fight at Mundesley while Hemera suffered a severe wound to a flipper at Overstrand Beach.
Sanctuary manager Nigel Croasdale said: “It’s been an unbelievably busy summer for us, with both our indoor hospital and outdoor convalescence pool more crowded than they have ever been before.
“Hopefully Artemis and Hemera are just the vanguard of what will be a steady stream of releases over the next few weeks.
“It will be a bitter-sweet moment when they head off into the surf but that is what the team work to achieve and in spite of the serious injuries they suffered we are confident both seals will cope just fine back in their natural environment.”
The remaining casulaties are common seals, which were born in the summer. Grey seals are winter breeders.
While seal numbers around the country are declining the populations are The Wash are booming.
