A new report examines the popular belief that pine cones can be used to predict upcoming rain. While some claim pine cones open up when dry weather is coming and close up when rain is on the way, experts say this is largely a myth not supported by scientific evidence.

Why it matters

The idea of using pine cones to forecast the weather has been around for centuries, but it's important to separate fact from fiction when it comes to weather prediction. Understanding the limitations of folk weather signs can help people make more informed decisions about how they prepare for changing conditions.

The details

The report looks at the biology behind pine cone behavior and why their opening and closing is not actually a reliable indicator of impending rain. Pine cones open and close in response to changes in humidity, not precipitation. As the weather gets drier, the scales on pine cones open up to release seeds. When humidity increases, the scales close back up to protect the seeds.
