Honolulu NOAA Tide Station 1612340

About NOAA station 1612340

The Honolulu station provides the primary south-shore Oahu water-level reference for the harbor, channels, reefs, surf zones, marinas, and offshore Pacific access.

Why people check this station

Anglers, surfers, boaters, and shoreline visitors use it to frame reef depth, harbor level, tide-pool access, channel stages, and the local high-low cycle.

How to interpret the prediction locally

Hawaii's modest tide range does not describe surf or reef-pass safety. Swell direction, trade winds, currents, and restricted or culturally important areas need separate checks.

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 1612340 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.
