Tidal streams are the periodic horizontal movement of water. These have the same astronomical causes as tides, which move in a vertical direction.

Sea level data recorded at the monitoring sites shown on the map is available for download.

The tidal streams in and around Cook Strait are unreliable and mariners are warned to exercise every precaution when navigating in the vicinity.

Let us know if you see a hazard or something you suspect will affect safe navigation, including anything missing from our charts or publications.
