When to go to Boa Vista: weather, wind, turtles and whales month by month

3 min read · October 2026

Boa Vista is a sunny island: you can go almost all year round. But depending on the period, neither the wind, the heat nor nature are the same. The right date depends on what you want to experience: pleasant days, wind for kitesurfing, turtles, whales… Here is a tour of the year with general markers (conditions vary from one year to the next).

Wind: friend or foe?

Wind is a constant on the island, with trade winds especially present from autumn to early summer. It is a blessing for board-sport fans and an ally against the heat, but it calls for a few habits: glasses and a scarf on sand tracks, a light jacket for stops at viewpoints, and sunscreen even when it feels cool.

Our rule of thumb: November to April for pleasant days, March to May for whales, August to September for turtles. In summer, favour morning outings.
