Trees are fascinating organisms. They cool our homes, inspire us daily, and even communicate with each other through their roots.

So, it might seem plausible that trees could also predict the weather.

According to an old wives’ tale, tree leaves turn upside down or show their undersides as a sign that a storm is approaching. But is there any truth to this?

Can Trees Predict a Storm?

Unfortunately, the idea that trees can predict storms by flipping their leaves is more fiction than fact. While it would be amazing if trees had this ability, the reality is that trees only respond to the weather conditions they experience. So, you’ll need to rely on your weather app, not the trees, to know when a storm is on the way.

Do Tree Leaves Really Flip Before It Rains?

Most of us have heard the story growing up—parents or grandparents saying that when leaves turn up, rain is coming. But as intriguing as that sounds, it’s not entirely accurate. After consulting with scientists from the Davey Institute, it's clear that this is more of a myth than a scientific fact.

While many people claim to have witnessed leaves flipping before a storm, there’s no scientific research to support this phenomenon. Trees don’t have a physiological reason to flip their leaves, even with an increase in humidity.

Why Do Leaves Sometimes Show Their Undersides Before a Storm?

So, if trees aren’t flipping their leaves to predict rain, why do we sometimes see their undersides before a storm? The answer lies in the wind.

Before a storm, a significant shift in wind direction can cause the leaves to turn over, making it look like they’re predicting the weather. But in reality, they’re simply being moved by the wind.

While you’re observing your trees, it’s also a good time to check if they’re getting enough water. If you notice curling or browning leaves, your trees might be thirsty!
