Roughly halfway between Brazil and Africa, the São Pedro and São Paulo archipelago rises from abyssal water where whale sharks appear on research and sport-fishing expeditions each boreal spring. Possible reproductive significance makes the site scientifically important, yet access demands long offshore passages and calm weather windows. May offers the most focused seasonal activity.

Possible reproductive significance makes the site scientifically important, yet access demands long offshore passages and calm weather windows. May offers the most focused seasonal activity.
Up to 62% sighting chance in São Pedro and São Paulo Archipelago. Best months: May, June.
Access is extremely limited. Trips are expedition-style with multi-day offshore passages from Natal or Fernando de Noronha and require Brazilian navy authorization plus calm weather windows.
Researchers suspect the mid-Atlantic archipelago may play a reproductive role, with equal numbers of males and females appearing each boreal spring, rare at most aggregation sites.
May and June are the most cited months for whale shark presence, though expedition schedules depend on navy clearance and Atlantic swell.
Multi-day sport-fishing and research charters typically run 8,000 to 15,000 BRL per person (2026 prices), excluding flights to Natal or Noronha and navy permit fees.
Most expeditions depart from Natal or stage through Fernando de Noronha before the long open-ocean crossing to the rocky mid-Atlantic outcrops.
