What the wind does on Boa Vista
Boa Vista is the third-largest island in the Cape Verde archipelago, sitting about 600 kilometres west of Senegal in the central Atlantic. Sal Rei, the island's small capital, opens onto a long, sandy bay sheltered from the open swell by a chain of offshore islets — the geography that makes Sal Rei the island's main kite base. Boa Vista feels noticeably less developed than its more famous neighbour Sal: the island has more empty beach per square kilometre than nearly anywhere else in the Atlantic kite circuit.
The dominant wind is the north-easterly trade wind — the same Alisios flow that drives the Canary Islands and continues south through Cape Verde toward the equator. At Sal Rei the trade is side-cross at the main bay and noticeably accelerated by the geography of the archipelago. Strengths of 18 to 28 knots are typical from late October through May; the windiest months (January and February) often deliver 25+ knot averages over multi-day stretches. Wind on roughly 25 days out of 30 is normal in the peak trade-wind window.
The season runs opposite to European summer — October through May is the trade-wind season, with peak strength December through March. June through September is the off-season: the trades soften, the inter-tropical convergence zone moves north and brings heat and humidity, and many kite schools reduce operations or close entirely. Boa Vista's value proposition is being a winter kite destination from a European perspective; it is the natural antidote to a windless European November.
