Bears hibernate during winter, but aren't sleeping the whole time. Hibernation for bears simply means they don't need to eat or drink, and rarely urinate or defecate (or not at all). There is strong evolutionary pressure for bears to stay in their dens during winter, if there is little or no food available. But bears will leave their dens on occasion, particularly when their den gets flooded or is badly damaged.
Weather does play a role. In the colder, northern parts of Alaska, bears hibernate about 7 months of the year. Bears in the warmer, coastal regions of the state hibernate for 2-5 months, with the longer hibernation time for bears raising newborn cubs.
