Ocean Waves
NOAA WAVEWATCH III

Coverage: Global oceans · Update frequency: Every 3 hours · Format: GRIB2
Overview
NOAA's WAVEWATCH III is a third-generation spectral wave model that provides forecasts of wave height, period, and direction. The model covers global oceans and is updated every 3 hours.
How Sentinela Uses This Data
Significant wave height is displayed as a color-coded ocean overlay, from calm (blue) to extreme (red). This helps mariners and coastal communities understand sea conditions.
Data Processing
Wave data is fetched from NOAA servers in GRIB2 format. We extract significant wave height and render as a semi-transparent overlay over ocean areas.
Limitations & Considerations
Model resolution may not capture wave conditions in complex coastal areas. Actual wave heights can vary significantly over short distances due to local bathymetry and wind patterns.
