What is the best tide to see whales and puffins

They don't go by tide. All depends on if you see any if not will give you other ticket for next one for free

If you don't see whales you will be given a ticket good for up to 3 years fron that date to try again free.

It's all a roll of the dice. I didn't see any whales. You are guaranteed to see Puffins.

Tide doesn't matter
