What Is Tide & Wave Height Data?
Tide and wave height data consists of real-time measurements collected from tide gauges and wave buoys deployed across coastal regions. These systems monitor critical ocean parameters including water levels, wave heights, atmospheric pressure, and wind speed, creating a comprehensive picture of coastal hydrodynamic conditions. The data is essential for understanding long-term sea level change, assessing flood risks, and tracking coastal erosion patterns. Data buoys and tide gauge networks form the backbone of coastal ocean intelligence. Modern approaches combine historical observations from established networks like NOAA's National Water Level Observation Network (NWLON) with advanced computer models to fill gaps in historical records and create continuous reanalysis datasets. This integrated approach enables better assessment of current conditions relative to historical baselines, particularly valuable in areas where observational data is sparse. Applications span scientific research, navigation safety, disaster management, and renewable energy assessment. The data supports climate change monitoring, supports infrastructure planning for coastal communities, and informs both public and private sector decision-making around coastal risk management.

FAQ
Common questions.questions.
What is the difference between tide gauge data and wave buoy data?
Tide gauges measure water level changes (tides and storm surge) at fixed coastal locations, while wave buoys measure wave height, period, and direction in deeper water. Tide gauges track vertical water movement; buoys capture the dynamic energy of ocean waves. Together, they provide complementary views of coastal ocean conditions.
How is historical tide and wave data validated?
Modern coastal reanalysis approaches combine historical observations from established networks like NOAA's NWLON with advanced computer models. Validation occurs through comparison with independent methods such as airborne LiDAR measurements and cross-checking between nearby stations to ensure consistency and accuracy.
Who owns and maintains tide gauge and wave buoy networks?
Government agencies like NOAA maintain primary networks such as the National Water Level Observation Network in the United States. International coordination occurs through networks like the Global Sea Level Observing System. Private research institutions and energy companies also deploy buoys for specific applications.
What are the main uses of tide and wave height data in renewable energy?
Wave and tidal energy developers use this data to identify optimal locations for oscillating water columns, tidal turbines, and tidal barrages. Accurate wave height and tidal flow measurements enable resource assessment, device design optimization, and long-term energy generation forecasting for power generation and desalination applications.
