Samana is surrounded by saltwater on all three sides of its coast. The southern coast of Samana extends into the bay of the same name, while the northern and eastern coasts directly face the Atlantic Ocean. The water temperature in the Atlantic Ocean here remains a pleasant +26-30°C year-round. These conditions make it ideal for swimming, especially considering the numerous inviting beaches and the peninsula's protection from strong winds.
With the Atlantic Ocean's temperature matching that of Samaná Bay, all of the peninsula's beaches offer equally comfortable water temperatures.
The size of the waves in the Atlantic Ocean along Samana's coastline varies depending on the specific beach you visit. Some beaches offer calm waters, resembling a tranquil swimming pool, while others boast larger waves. These bigger waves are highly appreciated by enthusiasts of surfing and other water sports, which are plentiful in Samana.
The ocean tides near Samana are generally not too pronounced and have minimal impact on activities like swimming, windsurfing, or kite surfing. However, during the rainy season, the tides may become somewhat more significant. It's possible that this change in the amplitude of ocean water movement attracts humpback whales to the area during this time.
