Thanks!
As mentioned the lube in your freehub is too thick for the cold. It's easy to fix if you're capable of overhauling your hub. Pull the axle and freehub. Pry off the rubber seal on the spoke side of the free hub and drip in some synthetic motor oil, I use 5-30 wt. in the winter, let it sit a bit and drip in some more. Put the hub back together and you might as well use a thin winter grease for the bearings too. I'm assuming your hub is Shimano? Others may or may not have the rubber seal that you will be able to remove.
I do this to all our bikes and it seems to work just fine in the summer with this oil too. Park tools website can give you instructions on taking your hub apart if you aren't familiar with doing this. Good luck!
