The planet orbits a K-type star. Basically same gravity as Earth's, with similar atmosphere. I'd like it to have a 30-hour day, plus in my characters' region, occasional very bad thunderstorms. Think winds of 60 mph, bad lightning, and maybe even a very precipitous drop in temperature. Think summer thunderstorms on steroids. It has flash floods.
The years will be shorter, yes? Because it's closer to the star.
Other than that, I'm looking for a basically temperate climate. I'm only talking about a portion of the planet for the time being, because right now I'm not smart enough to talk about the size of the continents and what kind of oceans.
