Fall and spring are actually the worst for mold, not just deep winter. When temperatures hover around 50-70°F and humidity spikes from rain or melting snow, mold spores explode. I notice it most in my basement after a wet October or March—it's damp enough for growth but not cold enough to kill anything. The constant freeze-thaw cycle pulls moisture into walls, creating perfect breeding ground.
