One of the best ways to get good at swimming in the open water... Get out and swim in the open water! Swimming in the open water can often take some time to get used to. To be comfortable in the open water you need to get used to the feeling of swimming in a wetsuit, swimming in rougher water, swimming without lane lines, sighting for navigation, and different water temperatures. Best way to do this is to just get out with some friends and go for a swim. | Swim360
