What is the best fence for a windy garden?
Closeboard on concrete posts, set in properly sized holes, or a fence with deliberate gaps such as hit-and-miss or slatted. Vertical boards on horizontal rails hold their shape under wind loading where a lap panel flexes as one sheet and lifts out of its slots. A solid fence catches more wind, so the posts have to carry it.
Wind does not push a fence over so much as lever it. A 1.8m solid fence is a sail, and every gust is transferred down the boards, into the rails, into the posts and out into the ground. Everything that fails in a gale fails at one of those transfers: nails pulling out of a light panel frame, a panel lifting out of a concrete post slot, or a post snapping at the soil line where it was already weakened.
That is why construction beats material here. Closeboard distributes load across arris rails into posts, with two rails up to 1.2m and three above, and it can be fixed rather than dropped in. A lap panel is a single flexing sheet held only at its edges. If you are exposed, on a hillside, at the end of a terrace, or on the open edge of an estate where the wind runs across fields, closeboard on concrete posts is the specification that stays up.
The other approach is to stop fighting the wind. Hit-and-miss fencing alternates boards on either side of the rails, and slatted fencing leaves a deliberate gap between boards. Both let air through instead of catching it, both stay private from most angles, and both put far less load into the posts. On genuinely exposed plots, up towards Cleeve Hill or on the escarpment above Leckhampton, they are often the better engineering answer.
Whatever goes on top, the ground work decides the outcome. Posts to a proper depth, holes about three times the post width, a full collar of concrete finished proud and sloped away, and gravel boards keeping timber out of the soil. A modest fence installed properly survives storms that flatten a better fence installed quickly.
