Compare Low Tides at NOAA Stations

Pick up to 4 stations and see their predicted low tides side by side, date by date. The stations and conditions stay in the page's address, so you can share them.

Low tide conditions

ft

Feet above mean lower low water (MLLW). Use a negative number for minus tides.

Only in daylight?

Daylight is from sunrise to sunset at the station.

Days

Weekends are Saturday and Sunday in the station's local time.

A date in the station's local time.

Low tides by date

Add a station to compare its low tides.

How the comparison works

For each station, YepTidal lists the predicted low tides on the dates you choose that are at or below the height, in daylight if you ask for it, and on weekends if you ask for it. Each row is a date, and each low tide goes in the row of the station's own local date. A station with no matching low tide on a date shows None.

The times are NOAA's predicted times of the low tides, not windows of time. Daylight is from sunrise to sunset at each station.
