"When the oak comes before the ash,
Then be ready for a splash.
When the ash before the oak,
Then be ready for a soak."
We used to recite this little rhyme when we were children, but I don't remember if it ever accurately predicted the weather for the following summer.
Last week I compared an oak and an ash growing next to each other.
On the very unscientific basis of comparing just these two trees, then the ash is further forward than the oak and so we should expect a wet summer.
We'll just have to wait and see.
