The Wind Gauge is a hand-held measuring instrument from the Ala Industrial mod that reads wind speed in km/h exactly where the player stands, so the tower height for a Wind Turbine, Sky Mill, or Tempest Mill can be chosen before anything is built. The instrument needs no energy: hold the Wind Gauge and press Shift + right-click, and the action bar (the text strip above the hotbar) shows height, wind speed, weather, and sky state. The reading is always taken at the player's feet, never at the crosshair target, and a plain right-click is not intercepted, so placing blocks and opening machines stays unaffected. The chime's pitch rises with the reading, so while climbing a tower a strengthening wind is audible before the line has even been read.

The scale follows the single wind curve that drives every mill in Ala Industrial, so the number on screen cannot drift away from real generation. Wind is zero at sea level (Y 63) and below, builds toward the clouds, and peaks in a narrow band right under the cloud deck: at Y 192 the Wind Gauge reads 62.5 km/h in clear weather, 93.8 in rain, and 125.0 in a thunderstorm. Above the clouds the air thins — at Y 248 and higher only a 3.8 km/h trace remains, and a tower at Y 230 is weaker than one at Y 127. A closed sky reads 0.0 km/h at any height, with leaves and cobwebs counting as cover, and in the Nether or the End the Wind Gauge reports that there is no wind at all. The recipe stays early-game: two sticks, one glass pane, two tin ingots, and two wooden gears. The Wind Gauge works identically on Fabric and NeoForge for Minecraft 26.2 (Java Edition).
