April sighting statistics

The month of April has been really good this year for whale watching in São Miguel. This month we have seen 11 cetacean species: 6 whale species and 5 dolphin species! This is the month that the baleen whale species are passing the Azores, so we have seen many of these, especially Sei whales. We are also starting to get many sperm whale sightings (almost 50% of the days we went out in April), which is a good sign that summer is on its way. The above graph shows the sighting frequency of the species we saw in April:


  • Common dolphin (Delphinus delphis)

  • Bottlenose dolphin (Tursiops truncatus)

  • Striped dolphin (Stenella coeruleoalba)

  • Risso´s dolphin (Grampus griseus)

  • Pilot whale (Globicephalus macrorhynchus)

  • Sperm whale (Physeter macrocephalus)

  • Humpback whale (Megaptera novaeangliae)

  • Blue whale (Balaenoptera musculus)

  • Minke whale (Balaenoptera acutorostrata)

  • Sei whale (Balaenoptera borealis)

  • Fin whale (Balaenoptera physalus)
