OpenMeteo Get Marine Forecast

Overview

Get marine/ocean weather forecast for any coastal or offshore location using Open-Meteo (free, no API key). Returns wave height, wave direction, wave period, swell wave height, swell direction, swell period, wind wave height, and ocean temperature. Data sourced from NOAA GFS Wave, DWD ICON Wave, and ECMWF WAM models with global 0.25 degree resolution. Useful for surfing, sailing, fishing, offshore operations, and maritime safety. Latitude/longitude required (use OpenMeteo_geocode_location for coordinates).
