When we do have currents, they are usually very mild and are always a longshore current (running parallel to the shoreline). The average current you might encounter on a given dive site will be anywhere from no current to approximately .25-.50 knot…very mild and easy to swim against, especially with fins on. The strongest current we can ever remember encountering was maybe a 1-1.5 knot current but that is extremely rare. However, it is always recommended to check the current when you first begin your dive or snorkel and always begin your dive against the current so that the last half of your dive will be with the current and you can just float back to your exit point. Just look at the soft corals and they’ll tell you which direction the current, if any, is flowing.
