The number of whales, dolphins and porpoises spotted has increased due to more people looking out for them.
The Sea Watch Foundation has invited more people to record their sightings or marine wildlife.
Tom Felce, Director of the Manx Whale and Dolphin Watch says for scientific purposes surveys are always conducted at this time of year.
He says it's still too early to tell if the numbers of animals in our waters is changing:
