In fluid dynamics, wind wave modeling describes the effort to depict the sea state and predict the evolution of the energy of wind waves using numerical techniques.These simulations consider atmospheric wind forcing, nonlinear wave interactions, and frictional dissipation, and they output statistics describing wave heights, periods, and propagation directions for regional seas or global oceans.
NOAA Wavewatch III 120-hour wind and wave forecast for the North Atlantic Main articles: Ocean dynamics and Wind wave model The transfer of energy between the wind blowing over the surface of an ocean and the ocean's upper layer is an important element in wave dynamics. [ 27 ]

An example of 500 mbar geopotential height and absolute vorticity prediction from a numerical weather prediction model Main article: Numerical weather prediction The basic idea of numerical weather prediction is to sample the state of the fluid at a given time and use the equations of fluid dynamics and thermodynamics to estimate the state of ...
There are many websites that provide predictions of the surf quality for the upcoming days and weeks. Wind wave models are driven by more general weather models that predict the winds and pressures over the oceans, seas, and lakes. Wind wave models are also an important part of examining the impact of shore protection and beach nourishment ...
In general, wave quality for surfing is usually better with less wind. If there is wind, wave quality is better if the wind is blowing gently offshore (away from the coast, towards the water.) This offshore airflow helps to hold up the face of breaking waves slightly longer, allowing a surfer to have more time to maneuver on the face of the ...
A GFS computer model forecast of wind speed between Thursday morning and Friday evening. ... It states that damaging winds, flying debris, large waves and dangerous driving conditions are possible.
An example of a forecast product from the GFS, in this case a 96-hour forecast of 850 mb geopotential height and temperature. The Global Forecast System (GFS) is a global numerical weather prediction system containing a global computer model and variational analysis run by the United States' National Weather Service (NWS).
