Two Minke whales were seen in St Ives Bay in Cornwall and a group of 50 common dolphins was seen near Berry Head in south Devon.
Bottle-nose dolphins and porpoises were also seen off Lundy in north Devon and off north Cornish coasts.
The survey was conducted by the Sea Watch Foundation during August.
Groups of about 50 common dolphins were seen off the Channel Islands too.
BBC South West Environment Correspondent Adrian Campbell said: "The presence of larger schools of common dolphins is associated with good fish stocks.
"This snapshot of the whale and dolphin population suggests they are doing better here than some other parts of the UK."
