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.

1 credit per completed run

The same inputs also work from your code or an AI assistant. See For developers.

Questions about NOAA Tides and Currents

Can I run it with my own inputs?

Yes. Change the inputs in Studio and press Run, or send new inputs from your code, or ask a connected AI assistant.

Can I call this NOAA Tides and Currents tool as an API?

Yes. Send a POST request to /v1/query with your Fous API key and the inputs, and get JSON back.

How much does it cost?

Each completed run costs 1 credit. Failed runs without a completed receipt are free; completed work can remain charged if delivery is interrupted. 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. Some results are reused for up to 24 hours, and results that use your account or key are never reused. It was last verified on Sep 29, 2026.
