Riverton Rocks
Riverton Rocks Tide Poster
At the edge of the Foveaux Strait where the Tasman and Pacific meet, Riverton Rocks is one of New Zealand's southernmost surf beaches. The convergence of two great oceans creates powerful, consistent tides that have shaped this coastline for millennia — a true southern ocean experience.

How to read it
A year of tides, turned into a grid.
Each row is a month — July at the top, June at the bottom. Each column is a day. The dots show when high and low tides happen, and how big they are.
Bigger dots mean more extreme tides. Spring tides cluster around full and new moons, neap tides sit quieter in between.
Once you learn to read one beach, you can read any beach. The patterns are always unique to the location.
