NOAA Tides and Currents

Tide times, coastal water levels and water temperature

NOAA Tides and Currents provides coastal observations and predictions: tide times within 30 miles of prediction stations, latest levels within 50 miles of reporting stations.

Get tide times

Get high and low tide times at the nearest NOAA prediction station to a US coastal place, with local times and heights above mean lower low water. Locations farther than 30 miles from a prediction station are not covered.

Your information

Location

US coastal town, beach or harbor, for example Santa Monica or Boston Harbor.

More options

DaysOptional

Number of local days to include, 1 to 31, for example 3.

UnitsOptional

Height units, feet or metres, for example feet.

Start DateOptional

First local date to include (YYYY-MM-DD), for example 2026-10-03. Defaults to today at the station.

Questions

Is Fous affiliated with NOAA Tides and Currents?

No. Fous is not affiliated with NOAA Tides and Currents. This workflow reads the public tidesandcurrents.noaa.gov website and returns its data.

How much does it cost?

Each run costs 1 credit. With pay-as-you-go, a credit costs 1¢; monthly plans cost less per credit.

Do I need a NOAA Tides and Currents account?

No. You only need a Fous account.

How current is the data?

Fous gets the data from tidesandcurrents.noaa.gov when you run it; repeating the same request within a day may return the saved result. Fous checks this workflow automatically; it last passed a check on Sep 29, 2026.
