Where I live, it's flat, wet, and (most of the year) hot.
Winter in Eastern North Carolina is usually nice for riding (though today it was about 36ºF/2ºC and raining. Yuck.). It hardly ever snows, though when it does it's interesting -- we have no equipment or salt for dealing with it, nor skills for driving in it.
Summer here is pretty trying. Very humid and swampy. Get used to sweat.
This is a small city, but it's very sprawly and car-oriented -- most of the development has happened since 1960. To get around by bike, you need to put some effort into finding usable routes through back streets, parking lots, and the occasional off-road shortcut. You also need fairly robust vehicular cycling skills.
That said, the town is small enough that no two points are more than 25 minutes apart by bike. The central city is making a comeback. It's not bad!
