Nantucket Island NOAA Tide Station 8449130

About NOAA station 8449130

The Nantucket station represents water levels near the island harbor and provides context for Nantucket Sound, nearby shoals, beaches, rips, and Atlantic approaches.

Why people check this station

Boaters and anglers check it when planning harbor depth, beach and flat access, current around shoals, and trips where fog, swell, and limited shelter matter.

How to interpret the prediction locally

Tidal current around shoals and rips may peak or turn at a different time from high or low water at the gauge. Check current predictions and local navigation information separately.

Tide height is not current speed

A high or low prediction describes the expected water level at the gauge. Current can turn earlier or later in a nearby inlet, river, bridge opening, pass, or channel. NOAA publishes separate current predictions for supported locations, and local weather can move the observed level above or below the astronomical prediction.

Basic station-planning checklist

1. Confirm that station 8449130 represents the water you intend to use.
2. Note the predicted high and low times, heights, and overall range.
3. Check wind, waves, visibility, precipitation, and official warnings.
4. Allow for the local offset between the gauge and your exact location.
5. Verify actual water, access, navigation, and regulations before departure.

Planning only: Data can be delayed, unavailable, or unrepresentative of a nearby micro-location. Never use this page as a substitute for official charts, notices, warnings, or direct observation.
