Wind

Wind is an element that has appeared in every Worms game. Wind changes every turn, and it affects certain weapons like the Bazooka, and utilities like the Parachute. The strength of the wind ranges from 0-10, and can blow either left or right.

Description
If not accounted for, wind can interfere with weapon fire. Wind too far in the wrong direction may cause a Bazooka rocket to start moving in the opposite direction of fire, which can cause issues such as the wrong Worm being hit, or a bridge you needed to cross getting a new hole big enough to not be able to be crossed easily, or even at all without utility tools.

When taken into account, the boost provided can be used as a way to make your projectiles reach further than it normally can, or simply as a way to show off your aiming skills.

Wind can allow weapon fire to attack in an arc. This allows for attacks from wind affected weapons within an area enclosed in three directions, if it is strong enough in the opposite direction of the open side. It also allows for shooting through vertical gaps, which can be used to shoot at Worms blocked directly through a gap that isn't directly in the way of the Worm at an angle that is more extreme than could be allowed without wind. Both abilities are useful for Darkside tactics.

Indicators

 * In first generation games, two orange meters surrounding a "WIND" label act as the wind indicator. The wind will blow stronger to the left the more the left meter is filled, and vise versa for the right meter.
 * In second generation games, there are two black rectangles at the bottom right corner of the screen during game-play. This is the wind indicator. If there is a blue bar inside the black rectangle on the left, the wind is blowing to the left. If there is a red bar inside the black rectangle on the right, the wind is blowing to the right. The length of the blue/red bar represents the strength of the wind. The longer the blue/red bar, the stronger the wind. The strength of the wind changes every turn, and sometimes the direction of the wind, too. Rarely, both of the black rectangles have no blue/red bar inside them, indicating there is no wind at all.
 * In Worms Forts: Under Siege, the wind indicator is an arrow pointing in the wind direction (with up the screen for forwards and down it for backwards) in a circle and a number rating below it. If the currently selected weapon is unaffected by the wind, a red cross appears over the circle to indicate this.

Trivia

 * If you stand on top of another Worm and fire the Bazooka when there is no wind, the shell will simply go straight down. In 3D games however, this does not always happen.
 * It isn't obvious that the wind gauge is supposed to be a wind gauge in the Second Generation games due to the gauge having colors like the teams, and no label being given to the gauge. The First Generation games had it clearly labeled as a Wind gauge, while the later games generally had a Wind gauge label as well or had other thematic elements added to suggest it is supposed to represent the wind.
