In celebration, I thought I'd share a couple of my own haiku style poems, both of which were inspired by listening to the ocean at different times (though, I'm not sure why I'm bothering to say so, since you'd have easily figured that out by reading them).
This first one I wrote last year:
Sea birds call
Foamy waves crash
Cold wind howls
And this one I wrote more recently:
Youngsters laugh and play,
Splashing in the chilly sea,
Making watchers smile.
