I'm up in Fort Collins. From our house buying experience, winter is definitely an easier time. We started looking just before Thanksgiving 2012, we found a house by Christmas, and closed Feb 1 2013. We had plenty of houses to look at, and while we did have sort of a crowd of people on Saturdays all trickling in and out of the same houses, we offered under asking price on a house we love, after a week of thinking about it, and still were accepted.
Conversely, a few different friends bought in Summer 2013. One of our friends put in a backup offer on a house (higher than asking price, and within 30 minutes of looking at it), and only got the house because the initial offer fell through. His realtor called him at like 6:30 am, said "Their offer fell through! Come meet me at the house so you can tell them you have cash!", and he put in his offer again by 8 am. My other friends had similar experiences of having to put in an offer literally as soon as you walked through a house you like.
I'm sure the market has changed since then, and housing/apartment vacancy rates in northern Colorado are a little ridiculous (<2% around campus in FoCo), but if nothing else, rent a little longer and look for a house this winter. You might have a slightly easier time of it. Good luck!
