That's an excellent question! The image of a beautiful wooden bench in a garden is idyllic, but you're right to consider the practicalities of a rainy climate. The good news is, yes, wooden outdoor benches can be a fantastic and practical choice, but their success hinges on two critical factors: the type of wood you select and the maintenance you provide.
Not all woods are created equal for weathering the elements. For a damp environment, you must choose a wood that is naturally resistant to rot and moisture.
The top-tier choices are dense, oily hardwoods. Teak is the gold standard. Its natural oils make it incredibly water-resistant and able to withstand years of rain with minimal care, eventually aging to a distinguished silvery-gray patina. Cedar and Redwood are also excellent softwood options, containing natural tannins and oils that act as preservatives, giving them a strong resistance to decay and insect damage.
On the other hand, it's best to avoid porous softwoods like pine unless they have been pressure-treated. Untreated pine will quickly swell, crack, and rot when consistently exposed to moisture.
Even the most durable wood benefits from a little help. Applying a protective sealant, outdoor oil, or water-repellent stain is non-negotiable in a rainy climate. These products penetrate the wood, creating a barrier that repels water, reduces the wood's tendency to swell and shrink, and protects it from UV damage. Reapplying this finish every one to two years is the key to a long-lasting bench.
Furthermore, small design features can make a big difference. Look for benches with slatted seats instead of solid planks, as this allows water to drain through quickly rather than pooling. Also, ensure the bench has sturdy, raised feet to keep the main structure off the wet ground, improving air circulation and preventing premature rot.
In conclusion, a wooden bench is absolutely practical for your rainy climate if you are willing to invest in a high-quality, weather-resistant species like teak or cedar and commit to a simple, regular maintenance routine. The reward is a timeless, natural piece that adds warmth and character to your garden for years to come.
