Marine Weather Scraper — Waves, Swell & Sea Temperature

Get marine forecasts for any coast or ocean point with the Marine Weather Scraper. Enter coastal place names or coordinates and export the wave height, wave direction and period, swell, sea-surface temperature and ocean currents for each — one clean row per location as JSON, CSV or Excel.

Built for surf forecasts, sailing and boating tools, fishing apps, coastal operations and marine research, it turns raw ocean-model output into a structured dataset you can drop into any product or workflow.

What it does

• 🌊 Wave conditions — significant wave height, direction and period for any point.
• 🏄 Swell breakdown — separate swell and wind-wave height, direction and period.
• 🌡️ Sea-surface temperature — water temperature for swimming, fishing and operations.
• 🧭 Ocean currents — current velocity and direction where available.
• 📍 Name or coordinates — type "Bondi Beach" or pass exact offshore coordinates.
• 📤 Export anywhere — JSON, CSV or Excel, or straight into an app, alert or dashboard.

Example output

{
  "name": "Honolulu",
  "latitude": 21.28,
  "longitude": -157.83,
  "time": "2026-09-21T12:00",
  "waveHeight": 1.36,
  "waveDirection": 131,
  "wavePeriod": 8.85,
  "swellWaveHeight": 0.84,
  "seaSurfaceTemperature": 27.4,
  "timezone": "Pacific/Honolulu"
}

How to use it

1. Add coastal place names (one per line) and/or exact coordinates.
2. Optionally adjust the current variables and add hourly or daily series.
3. Run, and download the results as JSON, CSV or Excel.

Input fields

Field	Description
Places (by name)	Coastal place names to resolve and look up (e.g. Honolulu, Nazaré).
Locations (by coordinates)	Exact {name, latitude, longitude} objects for precise offshore points.
Current variables	Which current metrics to include (wave height, swell, sea temp…).
Hourly variables	Optional hourly series (leave empty for current conditions only).
Daily variables	Optional daily aggregates (wave height max, dominant direction…).
Forecast days	Days of hourly/daily data to fetch, 1–7.
Timezone	auto for each location's local time, or an IANA name like Pacific/Honolulu.

Output fields

name, query, latitude, longitude, country, admin1, timezone, time, waveHeight, waveDirection, wavePeriod, windWaveHeight, windWaveDirection, windWavePeriod, swellWaveHeight, swellWaveDirection, swellWavePeriod, seaSurfaceTemperature, oceanCurrentVelocity, oceanCurrentDirection, current, hourly, daily, scrapedAt.

Popular use cases

• Surf forecasting — show live wave height, period and swell for each break.
• Sailing & boating — plan passages around wave and current conditions.
• Fishing apps — combine sea-surface temperature with wave state.
• Coastal operations — monitor sea state for ports, works and safety.
• Research & analytics — build multi-point marine datasets over time.

FAQ

Do I need an account or key? No. Enter your places or coordinates and run.

Which conditions are included? Wave height, direction and period; separate swell and wind-wave components; sea-surface temperature; and ocean currents where available.

Why did an inland point return nothing? Marine data covers oceans and coasts. Use a point on or near the water.

Can I get an hourly or daily forecast? Yes — add hourly and/or daily variables and set the number of forecast days.

Can I export to Excel or Google Sheets? Yes — results download as JSON, CSV or Excel and integrate with apps, alerts and dashboards.
