Pine cones can be used to predict the weather -fact!
Why do they do this? It is a survival thing. The pine cone wants to protect the seeds it has grown and release them just at the right time. To maximise and provide them with the best chance for the future, the pine cone uses the humidity of the local environment (warm and dry) but how do they do this when the pine cone scales are made up of dead cells? So, before you go spending your money on a wireless weather station, have a look at this and see if you can use pine cones (nature) in your setting instead.
