The strait is named after James Cook, who was the first European commander to sail through it. Its Māori name is Te Moana-o-Raukawa. The strait has an average depth of 128 metres (420 ft). The strait can be dangerous and unpredictable, because of the tide patterns and the weather. The most common way to get across is by ferry.

When it is high tide on one side of Cook Strait, it is low tide on the other side. For this reason, the strait can experience exceptionally fast tidal flows.
