NOAA Tides & Water Level Data API

Open the NOAA Tides & Water Level Data API in the Apify Store

Local preparation only

This candidate is locally implemented and fixture-tested. It remains unpublished until the separate external-sync/build/run/publication approval gate is cleared.

Try this first

Retrieve high/low tide predictions for The Battery, New York:

{"stations":["8518750"],"product":"predictions","date":"recent","interval":"hilo","datum":"MLLW","timeZone":"lst_ldt","units":"english","maxResults":20}

Buyer intent

Retrieve station-specific tide predictions and water-level observations for maritime operations, coastal dashboards, port analytics, and repeatable data workflows. This is distinct from weather alerts: output is station/time-series water data, not warnings or forecasts.

{"stations":["8518750"],"product":"predictions","date":"recent","interval":"hilo","datum":"MLLW","timeZone":"lst_ldt","units":"english","maxResults":20}

Reliability and limits

• Official NOAA CO-OPS Data API only; JSON GET requests, no browser, proxy, login, CAPTCHA, or paid service.
• One bounded request per station, at most 10 stations and 500 output records per run.
• Three retries for transient HTTP failures, 30-second request timeout, deduplication, structured partial-record rejection, and at least 1,000 ms between station requests.
• NOAA documents product-specific date limits and throttling guidance; keep date ranges small and do not attach high-frequency schedules.

Output

Each dataset item includes station, product, timestamp, value, units, datum, optional flags, the exact official request URL, retrieval time, and a non-affiliation disclaimer. No contact or other personal fields are requested.

Source and rights gate

NOAA CO-OPS Data API: https://api.tidesandcurrents.noaa.gov/api/prod/. NOAA documents station-based observations and predictions, JSON output, product-specific limits, and throttling guidance. NOAA public-data guidance supports reuse unless specifically annotated otherwise; this Actor credits NOAA, disclaims affiliation, and does not present output as official navigation or safety guidance. External publication remains owner-gated.

Pricing hypothesis

• Actor start: USD 0.00005
• Tide/water-level record: USD 0.001
