env_wind is a point entity available in all 
Source games. It creates wind throughout an entire map, which affect physics props, swaying trees, and dust.
Important:This is a preserved entity in .If the game has round restart mechanics this entity may not behave as expected:
- On a new round entities with this classname will intentionally not reset. You can use logic_auto to emulate resetting it.
- Killing it removes it forever, as it is not respawned on a new round.
- It cannot be spawned with a point_template.
- Parenting this with non-preserved entities may have undesirable effects.
Note:Wind direction is determined by env_wind's yaw value.Note:In most games, this entity is required for $treesway to have any effect, unless $treeswaystatic (only in ) is used.Bug:The wind effect in the client game will not reset when a new map is loaded which does not contain an env_wind entity.

parentnameortarget).
Also displayed in Hammer's 2D views and Entity Report.See also: Generic Keyvalues, Inputs and Outputs available to all entities
- Min normal speed (minwind) <integer>
- Minimum speed of the wind while idling.
- Max normal speed (maxwind) <integer>
- Maximum speed of the wind while idling.
- Min gust speed (mingust) <integer>
- Minimum speed of wind gusts.
- Max gust speed (maxgust) <integer>
- Maximum speed of wind gusts.
- Min gust delay (mingustdelay) <integer>
- Minimum time delay between random gusts.
- Max gust delay (maxgustdelay) <integer>
- Maximum time delay between random gusts.
- Gust Duration (gustduration) <integer>
- How long will the wind gust for.
- Max gust dir change (degrees) (gustdirchange) <integer>
- Maximum amount that the wind's direction changes due to a gust.
- Radius (windradius) <float> (only in )
- The radius this entity applies wind effects to. -1 for global effect.
Inputs
- Enable (only in
) - Turns the wind on.
- Disable (only in )
- Turns the wind off.
Outputs
- OnGustStart
- Fired when a wind gust begins. Bug:env_wind gusts can seemingly pile up and fire this output multiple times when a player first loads into a multiplayer map.
Workaround:Use AddOutput to add OnGustStart effects when players are already connectedTodo: Needs more testing, only observed in[todo tested in ?]
- OnGustEnd
- Fired when a wind gust ends.
