Multi-model comparison

Compare side by side. See where forecasts agree.

Every model tells a slightly different story. Surfcast overlays ECMWF, GFS, MFWAM and DWD on the same chart, so you can spot consensus — and back yourself when they disagree.

Good to know

Questions, answered.

Where does the forecast data come from?
Surfcast pulls from established global marine models — ECMWF (WAM), NOAA GFS Wave, Météo-France MFWAM and DWD GWAM — plus tide data, so you're reading the same science the pros rely on.
Which regions are covered?
Coastlines worldwide. Search by country, region or spot name, browse breaks near you, or explore the live map to find anywhere with rideable swell.
Is there a home-screen widget?
Yes. Pin any spot to a widget and see live wave height, period, wind and the full day's tide curve without opening the app. Lock-screen widgets show the tide, swell and wave energy without even unlocking your phone.
