When is the Best Time to See Whales in Maine?
Maine's pristine coastal waters offer some of North America's most spectacular whale watching opportunities. The best time to see whales in Maine is from May through October, with peak activity occurring between June and September when multiple species migrate through the Gulf of Maine's nutrient-rich waters.
During these prime months, visitors can expect to encounter humpback whales, finback whales, minke whales, and occasionally the endangered North Atlantic right whale. The combination of warmer weather, calmer seas, and abundant marine life creates ideal conditions for both whales and whale watchers.
