How To Use a Weathervane

A weather vane is a simple device that is used to measure the wind's direction of blowing. For ordinary individuals, this device can be a great help for them to determine the weather without relying to weather forecasts from the news or television. If you are interested in putting up and using your own weather vane, follow these steps.

  • Before you can even derive results from your weather vane, you have to be knowledgeable on its functions. Most people put up their weather vanes without having enough understanding on how weather vanes actually work that is why most of the time they obtain wrong data.
  • Decide the suitable location where you can put up your weather vane. Since the purpose of the weather vane is to calculate the direction of the wind, it is best to set it up in high areas such as your house's roof, garage, barn or green house. It is also important to keep your weather vane away from any huge objects that can impede or control the wind's direction. In addition, use a strong material for your weather vane since it will be dealing strong winds once it is installed. So better put it in the highest site and clearest area in your house or property.  
  • As stated earlier, weather vanes are used to evaluate the route of the wind. With this, you will need a compass in order for you to draw from the four major directions of the wind namely north, south, east and west. When you are putting up your weather vanes, it is best to use a compass to make sure that each pointer is set in the right direction. Once you have installed your weather vane, create a data of every direction for your reference in the latter part.
  • Test your weather vane when the wind is blowing to find out which path the weather systems are approaching. Your weather vane's arrow will point out the direction where the wind is blowing. Hence, when the arrow points toward the east, then you have to expect that you will be receiving westerly wind since it is the direction where the wind is coming from.
  • Observe the wind's direction. The normal wind systems in several states in the United States come from the west to the east. Therefore, if you are located in the eastern part of the U.S, the wind might approach off the Atlantic Ocean and goes from east to west.  
  • Supervise your weather vane often. Record the directions of wind from time to time to observe the local weather system. Include in your record the environment each time you write the direction such as the shapes of clouds, color of the sky, temperature and the like. Evaluate your log every week and note any evident patterns you find out. With this, you will be able to monitor regional movements that will let you calculate the weather in your location.

One of the oldest weather-measuring apparatus is the weather vane. This is very useful in illustrating the direction of weather systems that will help you foresee the weather accurately.
