Whale watching season in Maine begins in the middle of April when the waters begin to heat up. Whale watching season ends near October when the weather cools back down and the whales move south. Whales enjoy the warm summer months to fish, plankton and sand eels.
Some whales that are often seen during Maine's whale watching season are finback whales, minke whales, humpback whales and pilot whales. The largest whale often seen is the finback whale, which can be up to 80 feet long. Occasionally, visitors are able to see orca, sperm and sei whales, though they are less common. Whale watching is better done on a whale watching cruise, but some visitors can see them from the shore with a good pair of binoculars.
