To weatherproof a wooden bench for winter, start by applying a waterproof sealant or wood preservative to protect it from moisture and snow. Cover the bench with a breathable outdoor furniture cover to shield it from rain, snow, and ice. Elevate the bench slightly off the ground to prevent water from pooling around the legs. If possible, store the bench indoors during the winter months, especially in areas with extreme cold. Regularly check for cracks or damage and reapply protective finishes as needed to maintain its weatherproofing.
