The period most favorable for observing cetaceans off the Maine coast extends from approximately mid-April to October. This timeframe represents the convergence of several factors, including the migration patterns of various whale species and the availability of their primary food sources within the Gulf of Maine.
Understanding the optimal viewing period allows both researchers and recreational observers to maximize their opportunities for successful whale sightings. This predictability also benefits the local tourism industry, enabling businesses to plan and promote whale watching tours effectively. Historically, maritime communities have relied on knowledge of these marine mammal movements, though now observation is primarily for conservation and leisure rather than exploitation.
