Boa Vista

Wind-shaped dunes, Atlantic reef diving and protected loggerhead nesting beaches

When to go

Best time to visit Boa Vista

For the widest mix of documented scuba and guided snorkeling, start with May-October, but do not mistake an operator product season for reliably calm daily seas.

Best overall window

May to October for a mixed scuba, snorkel and island trip

These are indicative months for planning, not a climatological safety assessment or provider schedule.

Outside that window

A local operator markets April-November scuba, but its island-specific and tour pages conflict on months and departure base; request trip-by-trip confirmation.

Choose your trip style

Start with the overall answer, then switch only when scuba, freedive, snorkel, or topside timing changes the trip in a meaningful way.

Seasonal cautions

Dec to Mar: Winter seas can reduce or suspend departures even when activity pages still display products.
Aug to Oct: Occasional rain and track disruptions are possible; do not infer daily weather or visibility from month alone.
Jun to Oct: Priority nesting beaches are legally protected during biological nesting; authorized visitor access and activity restrictions differ from ordinary beach tourism.
