Visibility Breakdown
Visibility by position
Solid = diver report · outlined = today's forecast
Post Break: The range past where any waves are forming, where the water starts to have a significant increase in visibility. There might be some sediment here, but swell energy is diffused and the water is calmer.
Open Water: This zone is far out enough from the shore that the water is at its clearest. It’s deep enough that sediment is not disturbed by the wave energy at the surface. Haze can sit near the surface, so the water is usually clearer the deeper you go.

About Nehalem Bay South Jetty
The Nehalem Bay South Jetty stands at the south side of the Nehalem River mouth in Tillamook County, reached from the Nedonna Beach neighborhood of Rockaway Beach. From US-101, Beach Street leads north through the Nedonna Beach neighborhood to a public parking area at the end of Section Line Street. The jetty itself lies roughly 1,000 feet across sand from the lot, a haul most divers make with a wheeled cart. The outer part of the jetty faces open ocean; the inner part sits inside the estuary channel. On a strong flood tide, divers who enter the estuary side can drift back well up into the Nehalem River system.
