Rough Seas out of NY/NJ to Caribbean? in Royal Caribbean International Posted March 28, 2020 · Edited March 28, 2020 by jetta8300 We have sailed out of NY 3 times, and yes, seas were rough, much rougher than any caribbean cruise. 2 of the sailings were to bermuda though, but the roughest sailing was from NY to Bahamas. There wasn't any storm in particular, but it was the most movement we have felt on any cruise to the point we actually wanted off the boat. Especially coming back. That sailing was in Mid-Late april.
