Observing the Wind and Air

Detect the direction of the wind. Wind is caused when air moves from a high-pressure area to a low-pressure area. Since weather moves in from the west, westerly winds indicate good weather because they suggest the bad weather is already to your east. Easterly winds suggest that the bad weather is coming toward you.

  • You can use grass or flower petals to determine the direction of the wind. Throw your grass or flower petals into the wind and watch the way that it blows or falls.
  • You can also detect the direction of the wind by wetting your finger and holding it out. The side of your finger that gets cool will tell you from which direction the wind is blowing.

Watch smoke from a fire. The air pressure determines what direction the smoke will go. In high pressure, the smoke will go directly up into the air. If the pressure is low, it will spiral back down around the fire. If you see the smoke spiraling back down, bad weather is likely on the way.

  • When smoke spirals downwards, it means that bad weather is very close. The low-pressure system is already in place over your area.

Watch for calm conditions. Before a storm, the low-pressure system can push out the area’s normal wind patterns. This creates a temporary calm before the storm begins. You’ll notice a lack of wind, which creates a stillness over the area. If you’re near water, it will be calm and still, as well. This calm indicates a coming storm.

  • At this point, you should be able to observe other signs of a storm, such as dark clouds.

    Take a deep breath. Close your eyes and smell the air. Smells become wet right before a storm, making them stronger. Before a storm, you should also notice a compost smell as plants release their waste. If you start to smell a compost scent, it likely means that a storm is coming.

    • If you are near a swamp, you will likely smell swamp gases right before a storm. Swamp gas smells like rotten eggs because it comes from decaying vegetation
