About Great Lakes Wave Monitoring

The Great Lakes coastal monitoring network provides critical wave and weather data for ocean safety, surf forecasting, and marine operations. These stations continuously measure:

  • Wave Height: Real-time significant wave heights and maximum wave measurements
  • Swell Periods: Wave period data essential for surf forecasting and marine planning
  • Wind Patterns: Wind speed, direction, and gust information affecting sea state
  • Marine Weather: Comprehensive ocean conditions for safe navigation and recreation

Whether you're checking surf conditions, planning a boat trip, or conducting marine research, the Great Lakes buoy network provides the reliable wave data you need for informed decision-making.
