NOAA Tide Predictions Scraper

🌊 NOAA Tide Predictions for Stations and Coastal Points

Marine operators, boaters, anglers, coastal planners, and developers can use this Actor to get official NOAA CO-OPS tide predictions as structured dataset rows. Choose stations or geographic points, set a prediction window and units, and use high and low events or hourly water levels in tide charts, schedules, and coastal tools.

• Request NOAA tide predictions for a station with NOAA Tides.
• Build a local chart with Tide Chart for My Location.
• Find a low-tide time for a submitted point with When Is Low Tide at My Location.
• Find a high tide for Galveston with High Tide Galveston Today.
• Prepare a local island chart with Tide Charts Anna Maria Island.
• Find official station context with NOAA Tide Stations.
• Request high and low predictions for coastal work with NOAA Tides and Currents Predictions.
• Plan a fishing window with Biloxi Tides for Fishing.

📊 Structured tide prediction rows

Each dataset row describes one predicted high or low tide event or one hourly predicted water level. Rows keep station identity, prediction time, level, datum, units, time-zone context, optional range and next-tide data, and direct NOAA source links.

▶️ Run predictions by station or geographic point

How it works

1. Choose high and low events or hourly predicted water levels.
2. Choose official NOAA CO-OPS station IDs or geographic points. A point is matched to its nearest official prediction station, and the row can show the distance.
3. Set the start and end dates, level units, vertical datum, and station local time or GMT / UTC. These settings apply to every station or point in the run.
4. Leave maxItems empty to return all available results until the source is exhausted, or set a positive cap across the run.
5. Run the Actor and open the dataset link in the run output.

⚙️ Input

Input fields

Field	Type	What it does
resultType	string	Selects highLow for predicted turning points or hourly for one predicted water level per hour.
discoveryMethod	string	Chooses whether the run uses official station IDs or geographic points.
stationIds	array of strings	Lists one or more official NOAA CO-OPS station IDs. Each uses the shared dates, result type, units, datum, and time zone.
coordinates	array of objects	Lists one or more latitude and longitude points in decimal degrees. Each point is matched to the nearest official prediction station.
coordinates[].latitude	number	Latitude of a submitted point in decimal degrees, from -90 to 90.
coordinates[].longitude	number	Longitude of a submitted point in decimal degrees, from -180 to 180.
startDate	string	Sets the first date in the prediction window in YYYY-MM-DD format.
endDate	string	Sets the last date in the prediction window in YYYY-MM-DD format. Use the same date or a later date than startDate.
units	string	Selects feet or meters for the chosen level value. Feet and meter values are kept when NOAA provides both.
datum	string	Sets the vertical datum for predicted levels, such as MLLW. Use a datum supported at the selected station.
timezone	string	Selects station local time or gmt / UTC for prediction timestamps. Rows include the station time zone and applied UTC offset.
maxItems	integer	Sets an optional positive limit on returned prediction records across the run. Leave it empty to return all available results until the source is exhausted.

Input example

This is the public input from a successful current-beta high and low prediction run. It leaves maxItems empty, so the source can return all available results.

💳 Pricing

Tide prediction

The Actor charges $0.00035 for each successfully saved normalized tide prediction. The charge applies when a prediction row is returned for a selected station and time window. A run that saves no prediction row has no tide-prediction event to charge.

🔌 Integrations

Call the Actor through the Apify API, then read the dataset link or the dataset API from the run output. Use the saved rows in tide charts, schedules, coastal planning tools, or other data workflows.

❓ FAQ

Can I use geographic coordinates instead of a station ID?

Yes. Choose geographic points and enter latitude and longitude in decimal degrees. Each point is matched to the nearest official NOAA prediction station, and the output can include the requested point and distance.

Can I request hourly predictions?

Yes. Choose hourly to receive one predicted water level for each returned hour. Choose highLow when you need predicted high and low turning points.

Does this return observed water levels or currents?

No. This Actor returns predicted tide events and predicted hourly water levels. It does not return observed or real-time water levels, currents, weather, waves, or swell.

What does the time zone setting change?

local returns station local prediction times. gmt uses GMT / UTC. Each row also includes the station time-zone name and the UTC offset used for the timestamp.

Why are feet and meters both in a row?

The selected unit controls level.value. The row also keeps feet and meter values when NOAA provides both, along with the vertical datum.

What happens when a station does not support my datum?

Use a datum supported at that station, such as MLLW. Datum availability can vary by station.

Can I leave maxItems empty?

Yes. An empty maxItems returns all available results until the source is exhausted. Set a positive value when you need a cap across the run.

Do I need a NOAA API key?

No. The Actor uses NOAA's public service and does not require a buyer-supplied API key or login.

Can I enter a place name instead of a station ID?

No. Use an official NOAA CO-OPS station ID or a geographic point. Natural-language place-name search is not an input option.
