Although it is considerably safe, waves and shifting water currents become especially hard to manage when you’re front-heavy and you don’t have your normal sense of balance. Plus, pregnant women get more easily dehydrated, something that can be exacerbated when hanging out under the sun. Consider wading when the water is placid, during low tide, or when it reaches no higher than your hip. Always have an able swimmer with you. Bring a water bottle so you can drink anytime mid-wade.
