Through the wetter months here, moisture is the main enemy - not ice, just steady damp that gets into unlubricated springs and hinge pins and turns a quiet squeak into a louder one over a few weeks. That's the time to actually lubricate, not just listen for noise and ignore it. When the occasional freeze does hit, that's when an already-fatigued torsion spring is most likely to snap, because cold steel has less give left in it. In the dry, warmer stretch of the year, wood-frame doors and sectional panels on older homes can shrink slightly at the seams, which sometimes shows up as a new rattle that wasn't there in spring. None of this means you need a different maintenance routine every few months - it means the same noise can mean different things depending on when you hear it, and a spring that's fine in August can be the one that goes in January.
