What Is the Best Month to See Whales in Kauai?
February is the best single month, inside a January to March peak. Kauai whale watch tours run from December to April, and mornings tend to have the calmest water and lightest wind, which makes blows easier to spot.

How Close Can You Get to Whales on Kauai?
Boats, swimmers and paddlers must stay 100 yards from humpback whales anywhere in Hawaii, and drones must stay 1,000 feet away. If a whale approaches on its own, the captain stops and lets it pass.

Month-by-Month Guide
The first humpbacks arrive. The zodiac tour starts its season, so book early in the month only if dates are flexible.
Whale numbers build fast. Competitive groups of males and frequent breaching.
The busiest month for whales and for bookings. Mothers with young calves stay near the surface.
Calves are older and more active. Still one of the best months to go.
Whales begin to head north. Early April is still good, late April is hit or miss.

Back at the dock after 2 hours (Super Raft) or 2.5 hours (zodiac).
Pack a dry shirt for the drive.Humpback Whale Behaviors to Watch For
A 40-ton humpback launches completely clear of the water. No whale watching experience in Hawaii matches this visual combination, the island's most dramatic wildlife moment.
The whale rises vertically, holding its head above the surface. From a zodiac raft at water level, a spy-hopping humpback is an unforgettable close encounter, the whale's eye is clearly visible.
A 15-foot white pectoral fin slapped repeatedly on the surface, a social or communicative display. The crack can be heard before the whale is seen.
The classic tail-up dive: each humpback's fluke is unique, like a fingerprint. From a zodiac raft at sea level, a fluking humpback is the quintessential Kauai whale watching image.
The tail stock raised sideways and slapped forcefully on the water in rapid repetition. Common during competitive male encounters in January and February as males challenge each other for position near females.
An aggressive competitive display: the whale arches its muscular tail stock out of the water and slams it sideways. Typically seen when escort males challenge each other near a female during peak heat-run season.
