Every spring, humpback whales migrate to the warm, shallow waters around Cape Verde to breed and calve. It is one of only a handful of known North Atlantic breeding grounds, and between March and May you have a genuine chance of watching a forty-tonne animal breach clear of the water.
When to go
The season runs from roughly March to May, with April usually the peak. Outside this window your chances drop sharply, so if whales are a priority, plan your trip accordingly — our month-by-month guide shows how the wildlife calendar fits together.
Best islands for whale watching
Boa Vista is the most established base, with trips leaving from Sal Rei harbour. Sal also runs excursions from Santa Maria, and whales are sometimes spotted from boats around Maio and Santiago. The shallow shelf between Boa Vista, Sal and Maio is the heart of the breeding area.
What to expect on a trip
Trips typically last three to four hours on a small boat. Guides look for blows, tail slaps and breaches, and often cut the engine to watch quietly. Mothers with calves are the most common sighting and frequently the most moving. Nothing is guaranteed — these are wild animals — but in peak season success rates are high.
Watching responsibly
Whales here are on a breeding ground with newborn calves, so behaviour matters. Choose licensed operators who keep a respectful distance, limit time with each group, approach slowly and never cut across a whale's path. Avoid boats that chase, crowd or promise swimming with whales.
- Book a licensed, responsible operator — ask about their approach policy.
- Take seasickness precautions; the swell can be significant.
- Bring a windproof layer, sun protection and a zoom lens if you have one.
- Manage expectations — sightings are likely but never certain.
