Scrapes high/low tide predictions from all 3,450 NOAA CO-OPS tide stations across the US — packaged for saltwater fishing, charter planning, and coastal activity scheduling.

Open NOAA public API — no API key required.

What it does

The actor fetches tide prediction data in two phases:

1. Station discovery — downloads the full NOAA CO-OPS station list (3,450 tide-prediction stations with lat/lon/state metadata)
2. Prediction fetch — retrieves hi/lo tide events per station for the requested date range

Each output record is one tide event (a single H or L) for a specific station and date. A typical day produces 3–4 events per station.

Use cases

• Saltwater fishing trip planning — identify optimal high/low tide windows for target species and locations
• Charter boat scheduling — feed tide windows into booking or planning apps
• Coastal tourism & recreation — beach, kayak, surf, clamming timing
• Marine research and data pipelines — bulk collection of historical or forecast tide data

Data source

Data comes from the NOAA Center for Operational Oceanographic Products and Services (CO-OPS) public API. The API is free and open — no authentication required. Coverage: 3,450 US tide-prediction stations spanning all coastal states and territories.

Predictions use the MLLW (Mean Lower Low Water) datum and are returned in local standard/daylight time (LST/LDT) for each station's timezone.

Notes

• No proxy required — the NOAA CO-OPS API is open and accessible without proxying
• Historical and future dates — the API supports both historical data and future predictions
• Subordinate stations (type S) use offsets from a nearby reference station; predictions are pre-computed by NOAA
• Large runs (all stations × multi-day range) will produce many records — set maxItems to control volume
