The short answer
Choose a NOAA reference that fits the location and water body. A nearby station’s times and heights are not automatically a beach-specific prediction.
A place label is only the starting point
Public Atlas associates a destination with a named NOAA reference station. Open the station link before using the prediction. Geographic proximity alone does not prove that a station represents a particular inlet, sound or beach.
Holden Beach example
Our Holden Beach page uses NOAA station 8659665, Bowen Point, Shallotte Inlet. That station label is preserved in the table and planner. A visitor going to another part of the shoreline should verify that the reference and NOAA guidance are appropriate for that destination.
Why a shared datum name is insufficient
Two stations can both use MLLW while their local reference elevations and tidal patterns differ. Treat a station’s predicted heights and times as belonging to that station. Do not transplant an offset from an unrelated location.
What to do when coverage is uncertain
Follow NOAA’s station information from the detail page. If the station relationship is unclear, use the official service or local authority to choose a reference. We avoid inventing beach-specific adjustments from distance alone.
Your next steps
- Destination: write down the actual beach or waterway.
- Reference: open the named NOAA station.
- Connection: check the station location and coverage.
- Uncertainty: do not apply an invented time correction.
Common questions
Can I use the nearest tide station for any beach?
Distance alone does not establish suitability. Check the station setting and NOAA guidance before applying its prediction.
Do stations using MLLW share the same zero?
No. MLLW is a local tidal datum; the same label does not establish a shared absolute elevation.
