## What's an Apify Actor?

Actors are web data automations that power AI and operations. They run on the Apify platform to scrape websites, process data, connect APIs, and automate workflows.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.
Actors are written with capital "A".

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.
The best way to integrate Actors is as follows.

- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

# README

## NOAA Tides & Currents — Tide Predictions Scraper

**Official NOAA tide predictions, water levels and tidal currents for any US coastal station — plus water/air temperature, wind and pressure — with station metadata baked in.** By station ID, for any date range. Free, keyless, no proxies.

Built directly on NOAA's official **CO-OPS** data API, so the tide data is authoritative and reliable — the actor adds multi-station batching, product switching and station-info enrichment on top.

### What you get

One flat row per reading, ready for datasets, APIs or apps:

- **Tide predictions** — high/low (`hilo`) or hourly water-level predictions with `time`, `value` and `type` (`high`/`low`)
- **Observed water level** — measured water level with `sigma`, quality `flags` and `quality` code
- **Tidal currents** — predicted current `velocity`, `type`, `bin`, `depth`, mean flood/ebb direction
- **Environmental products** — water temperature, air temperature, wind (with `direction`, `gust`) and air pressure
- **Station enrichment** (optional) — `stationName`, `state`, `latitude`, `longitude` on every row
- Configurable `datum` (MLLW/MSL/NAVD…), `units` (english/metric) and `timeZone`

### Output sample

Tide predictions (`product: "predictions"`, `interval: "hilo"`), station info included:

```json
{
  "station": "8454000",
  "product": "predictions",
  "stationName": "Providence",
  "state": "RI",
  "latitude": 41.8071,
  "longitude": -71.4012,
  "time": "2026-07-12 04:18",
  "value": 4.63,
  "type": "high"
}
```

Tidal currents (`product: "currents_predictions"`):

```json
{
  "station": "ACT0926",
  "product": "currents_predictions",
  "time": "2026-07-12 05:30",
  "velocity": 1.42,
  "type": "flood",
  "bin": null,
  "depth": null,
  "meanFloodDir": 45,
  "meanEbbDir": 225
}
```

### Input

| Field | Type | Default | Description |
|-------|------|---------|-------------|
| `stations` | array | `["8454000"]` | NOAA CO-OPS station IDs. Find them at tidesandcurrents.noaa.gov |
| `product` | string | `predictions` | `predictions`, `water_level`, `currents_predictions`, `water_temperature`, `air_temperature`, `wind`, `air_pressure` |
| `interval` | string | `hilo` | Predictions: `hilo`, `h`, `6`, `1`. Currents: `MAX_SLACK` |
| `datum` | string | `MLLW` | Vertical datum for levels/predictions |
| `date` | string | `today` | Quick range: `today`, `latest`, `recent` (ignored if explicit dates set) |
| `beginDate` / `endDate` | string | — | Explicit `YYYYMMDD` range |
| `range` | string | — | Hours from begin date (or from now) |
| `units` | string | `english` | `english` (feet) or `metric` (meters) |
| `timeZone` | string | `lst_ldt` | `lst_ldt`, `lst` or `gmt` |
| `includeStationInfo` | boolean | `true` | Enrich rows with station name/state/coordinates |

### Example input

```json
{
  "stations": ["8454000", "9414290"],
  "product": "predictions",
  "interval": "hilo",
  "beginDate": "20260712",
  "range": "72"
}
```

### Why this actor

- **Authoritative & keyless** — NOAA's own CO-OPS API, no key, no proxy, no anti-bot.
- **Two paying audiences at once** — fishing and sailing/boating apps both need clean tide data.
- **Breadth in one actor** — predictions, water level, currents, temperature, wind and pressure, multi-station, any date range.
- **Enriched** — station name, state and coordinates joined onto every row so you don't re-look-up.

### Pricing

Pay per result — **$1.50 per 1,000 results** (one reading = one result). No subscription or platform fees; you only pay for what you get.

### Related actors

- **Marine Weather Forecast Scraper** — waves, swell and marine conditions for sailing.
- **USGS Water Data Scraper** — river streamflow, gage height and water temperature for freshwater fishing.
- **Open-Meteo Weather Forecast Scraper** — general forecasts by city or coordinates.

### Notes

- Data is NOAA's official public CO-OPS API; the actor sets a descriptive User-Agent and retries on 429/5xx so results aren't dropped.
- Available products, datums and intervals vary by station — not every station reports every product.
- This actor is an independent tool and is not affiliated with or endorsed by NOAA.
