Frequently asked

Whale watching worldwide

The most common questions about whale watching, season by season.

  • Where can you watch whales around the world?

    Over 80 documented spots across every ocean: Húsavík (Iceland), Andenes (Norway), Tromsø (orcas), the Azores (sperm whales year-round), Hermanus (South Africa), Kaikoura (New Zealand), San Ignacio (Baja California), Mirissa (blue whales), La Réunion, Martinique, Guadeloupe and the Mediterranean (Pelagos sanctuary). The map shows active seasons month by month.

  • What is the best time to see whales?

    It depends on species and location. Humpbacks: December–May in the Caribbean and tropics, June–September in Iceland and Norway. Blue whales: December–April in Sri Lanka, July–October in Monterey Bay. Orcas in Tromsø: November–January. Sperm whales in the Azores: year-round. Right whales in Hermanus: June–November.

  • What whale species exist?

    Around 90 living cetacean species. Whale Spotter covers 30 key species: great whales (humpback, blue, fin, sperm, gray, right whales, bowhead, Bryde's, sei, minke), toothed whales (orca, beluga, narwhal, pilot whale) and dolphins (bottlenose, common, striped, Amazon river dolphin, harbour porpoise).

  • What is the fastest whale?

    The sei whale (Balaenoptera borealis) is the fastest of the great whales, exceeding 50 km/h in bursts. The orca follows at peaks of ~55 km/h on short distances. In travel mode most baleen whales cruise between 5 and 15 km/h.

  • What is the biggest whale?

    The blue whale (Balaenoptera musculus) is the largest animal ever to have lived: up to 30 m long and 190 tonnes. Its heart alone weighs 600 kg and its tongue weighs as much as an elephant.

  • How do you choose an ethical operator?

    Look for: respect of legal minimum distances (100 m for great whales, 300 m with calf), small groups, low speed, no chasing, no swimmers without permit, locally rooted, membership in a conservation label (WSAW, World Cetacean Alliance, EAAM). Check online reviews and the guide's background.
