Common Questions About Timing
What is the best time of day for whale watching? +
Morning is generally best as the ocean is often calmer, making it easier to spot "blows" on the horizon. However, sunset tours offer incredible lighting for photography.
Can I see whales in Kauai in December? +
Yes! Early December is "hit or miss," but by late December, sightings are quite common. It's a magical addition to a holiday trip.
When do the whales leave Kauai? +
Most whales depart by mid-April. By early May, the vast majority have begun their 3,000-mile journey back to the feeding grounds of Alaska.
