Be honest about your swim ability
Operators expect participants to be comfortable in open water and able to return to the boat without assistance; if unsure, ask about flotation options before booking.
Wear a wetsuit for comfort
Atlantic temperatures can be cool year-round; a 3/2 or 5/4 mm wetsuit extends comfortable swim time and reduces hypothermia risk.
Respect the animals' space
Do not touch, chase, or feed dolphins—let them approach on their own terms to avoid altering natural behaviors.
Watch sea state and motion
If you’re prone to motion sickness, take precautions; choppy conditions are common and can limit swim windows.
3/2–5/4 mm wetsuit
