Currently showing a built-in astronomical tide prediction — harmonic constituents with node
factors, fitted to 13 months of real Balanga tide tables and valid for any date, years ahead (one main
high tide per day ≈ 10–11 AM, spring highs ≈ 1.8–2.0 m). This is predicted data, not a live measurement.
For true LIVE data: get a free API key (e.g. WorldTides worldtides.info or
Marea api.marea.ooo), paste it in API key and the station endpoint above —
the app expects {"station": "…", "unit": "m", "measurements": [{"t": "ISO time", "h": 1.3}, …]}
and switches to LIVE automatically.
