A seasonal breakdown of what to expect during whale season
Whale season spans six months, but activity varies dramatically. Here's what to expect each month so you can time your trip perfectly.
The first humpbacks typically arrive in late November or early December. These early arrivals are usually pregnant females seeking the calm, warm waters to give birth. Sightings are less frequent but still exciting, and tours are less crowded. By mid-December, you can expect to spot whales on most days from popular vantage points.
This is peak whale season. The waters around Maui are teeming with humpbacks -- mothers with newborn calves, competing males engaged in dramatic heat runs, and lone singers producing their haunting underwater songs. The activity level during these months is extraordinary. On a good day from shore, you can see spouts and breaches in every direction.
January and February are the best months for seeing competitive groups -- pods of males jostling and lunging to win mating rights with a female. These heat runs are dramatic and fast-moving, with whales breaching, charging, and slapping the water in displays of strength. Book whale watching tours as far in advance as possible during these months.
March is arguably the best month for seeing mother-calf pairs. The calves born in January are now a few months old and full of energy, practicing their breaches and tail slaps in the protected channels. Mothers are patient teachers, and watching a young calf attempt its first breach is one of the most heartwarming things you will ever witness.
Overall whale numbers remain high in March, and the weather is typically excellent with calm seas. Many experienced whale watchers consider March the sweet spot -- fewer tourists than February, still packed with whale activity, and incredible calf interactions.
The whale population begins to thin as adults start the long migration back to Alaska's nutrient-rich feeding grounds. However, mothers with young calves are among the last to leave, waiting until their calves are strong enough for the 3,000-mile swim. April still offers good whale watching, and the reduced numbers mean more intimate encounters with fewer boats on the water.
By late May, most whales have departed, though stragglers are occasionally spotted into June. If you visit during these shoulder months, you may be rewarded with remarkably close encounters as the remaining whales seem less wary of boats.
