Yes, Cape Verde is notoriously windy in April, as this month falls within the tail end of the "Trade Winds" season (December to June). A supportive peer "weather" check: according to 2026 climate data, you can expect consistent northeast winds averaging 18 to 25 mph, with frequent gusts. While these winds make the islands world-famous for kitesurfing and windsurfing—especially on Sal and Boa Vista—they can make the "feels like" temperature significantly cooler than the actual 24°C (75°F) air temp. April is also part of the "dust" season, where the Harmattan wind can occasionally bring a fine haze of Sahara sand over the islands. If you are looking for calm, mirror-flat water for swimming, April might be challenging on the windward coasts; however, the wind provides a natural "air conditioning" that makes the intense tropical sun much more tolerable for hiking and exploring the volcanic landscapes.
