Shipwrecks and sanctuary reefs backed by Atlantic Forest waterfalls
Ilhabela diving is rewarding but demands situational awareness: a working channel with currents and boat traffic, plus open-ocean exposure on some sites. Use local operators, carry surface signaling gear, and treat conservation rules (especially in protected areas) as part of your dive plan.
Strong current and heavy boat traffic in the channel
The Sao Sebastiao Channel is a working waterway. Use surface marker buoys, obey dive-flag rules, and avoid freediving or snorkeling in traffic lanes without dedicated support.
Visibility can change fast after rain
Summer downpours can reduce visibility in a matter of hours. Keep dive plans flexible, accept site changes, and consider macro-focused dives when the water is green.
Borrachudos (biting midges)
These tiny insects are infamous in Ilhabela, especially near vegetation and at dusk. Bring strong repellent, light long sleeves, and treat bites early to avoid irritation.
Cold fronts and swell can cancel trips
In cooler months, weather can flip quickly with cold fronts. Plan backup land activities and do not overpack your schedule with non-refundable boat trips.
