Where Does the Weather Data Come From?

  • Land forecasts are powered by meteoblue, a leading provider of weather data around the globe. The forecasts are based on a multi-model approach , which combines various weather models with current measurements and observations as available, specifically for the location and elevation requested. The meteoblue website provides extensive additional weather information.

  • Marine forecasts are based on OCENS premium marine weather data which provide wave and wind levels to 1/100th of a degree lat or lon. Atlantic data sources include WW3 Multi-Global, WW3 Navy, NDFD, ECMWF, GFS Global Wave as well as HRRR and RAP for wind in some areas.
