A rip is a strong current of water running out to sea.
Waves normally wash up onto the beach and ebb back into the sea.
In some places the ebbing water forms a strong channel pulling out to sea. On many beaches the force of this escaping water can drag you far out to sea. This is called a rip. Permanent A permanent rip current will remain in the same area for months or even years. This is because the local ocean conditions change very little.
