Groundswell uses open, verified data sources for all forecasts. If a forecast looks wrong for your local spot, here are a few things to know:

• Wave data comes from the Open-Meteo NEMO marine model, updated hourly.
• Tide predictions come from NOAA CO-OPS and other official harmonic databases.
• Very localized conditions (reef breaks, harbors, river mouths) may differ from open-ocean model output.

You can review our data sources and live accuracy statistics on the Accuracy page.

To request a copy of your data, ask for deletion, or exercise any other GDPR right, email support@groundswell.surf with the subject "Data Request." See our Privacy Policy for full details on your rights.
