Get predicted high and low tide times and heights for any NOAA CO-OPS tide gauge station in the US, Puerto Rico, Pacific Islands, and Great Lakes. Returns a chronological list of high (H) and low (L) tides with UTC timestamps and water heights. Specify a station_id (e.g. 8443970 for Boston, 9414290 for San Francisco, 8518750 for New York) and optional date range (default: next 7 days). Datum defaults to MLLW (Mean Lower Low Water) — the reference datum used on NOAA nautical charts. Data is generated from harmonic tide predictions.
