Yes! You can leave your teak outside year-round. Teak wood is naturally waterproof and resists extreme heat and cold, humidity and dryness, sun, snow, and rain. However, if too much snow accumulates, the weight could damage your furniture. We recommend periodically removing the snow off your teak. When the snow melts, it will leave behind a residue of dirt that will need to be cleaned. To prevent this, you can either cover your teak (with a tarp or similar) or place it in an unheated storage space (such as in a shed or under a deck).
