Tile Directly Onto Wood Window Sill?

We have a small (1' deep, 2' wide) wooden windowsill above our kitchen sink, and I'd like to put tile over the wood to make it a bit more waterproof, because it gets quite a bit of water on it when we do the dishes. Can I put tile directly onto the wood, given that it's a pretty small, horizontal space? Or do I need to put something between the wood and the tile? I'd prefer to do it directly on the wood if possible so that we don't have to mess with moving the trim around. Thanks!

I believe I would look for a custom cut piece of solid surface to silicone down to the sill. Tiling that surface will cause it to crack, since wood is not as stable as concrete backer underlayment. The solid surface probably would not cost that much and you may even find a deal for a piece at a place that does installation. It cuts with jigsaw/circle saw and you can polish it with a random orbit sander and really fine paper (600+).
Here's an example we installed at a local college
