Wind is one of the most influential environmental factors affecting wildland fire behavior. The complex terrain of fire-prone landscapes causes local changes in wind speed and direction that are not predicted well by standard weather models or expert judgment. WindNinja was developed to help fire managers predict these winds.
WindNinja is a computer program that computes spatially varying wind fields for wildland fire and other applications requiring high resolution wind prediction in complex terrain. It was developed to be used by emergency responders within their typical operational constraints of fast simulation times (seconds), low CPU requirements (single processor laptops), and low technical expertise.

WindNinja can be run in three different modes.
- 1. User specified average wind speed and direction. (Domain Average)
- 2. User specified data from a weather station. (Point Initialization)
- 3. Coarse scale weather models from NOAA. (Weather Model Initialization)
WindNinja also requires elevation data, date and time, and dominant vegetation type. (WindNinja can obtain much of this data from internet sources)
WindNinja can run on Linux and 32/64-bit Windows (XP and higher) (Download Here)
