How to Anchor a Trampoline for High Wind | Secure It Right

Securing a trampoline against high winds requires auger-style screw anchors at every leg, connected with heavy-duty polyester ratchet straps — the only method that reliably prevents lift in severe gusts.

For the full breakdown, see our best Trampoline Anchors guide.

A trampoline left unsecured in a storm becomes a dangerous projectile. The force of a 50-mph gust against a 14-foot mat can generate over 200 pounds of lift, enough to flip even a heavy frame. While complete disassembly is the only hurricane-proof guarantee, the right anchoring system makes the difference between a safe backyard and an emergency call.

How Auger Anchors Work Against Strong Winds

Auger-style ground anchors — also called screw-in anchors — use helical blades that bite into the soil when twisted. Once installed at every leg, they resist upward pull by distributing force through the ground itself. For moderate gusts, wind stakes driven at a 45-degree angle toward the trampoline center provide extra hold. In sandy or loose soil, deep-spiral anchors that reach 18–24 inches underground offer the best grip.

Selecting the Right Straps and Stakes

Polyester ratchet straps are non-negotiable. Nylon webbing stretches noticeably under sustained wind load, letting the trampoline rise and rock before the strap finally stops it. Polyester’s superior strength-to-stretch ratio keeps the frame pinned to the ground when gusts hit. Use 1-inch or 2-inch wide straps with a working load limit of at least 500 pounds.

For the stakes themselves, the Penetrator 18-inch anchor from American Earth Anchors uses an 18-inch screw design with rust-resistant powder coating and PE-2P brackets made specifically for trampoline legs. In rocky soil where screw anchors won’t bite, hammer steel rebar stakes at 45 degrees and connect them to the frame using a quick-link and a stainless steel chain rated for 500–600 pounds working load. Never use knots — they slip under pressure.

Installation Steps for Maximum Hold

Every anchor must be driven to its full rated depth. Shallow placement is the most common failure point in real storms.

1. Position the anchor over the center of the trampoline leg so the center post sits firmly inside the anchor’s cradle. Repeat on the opposite leg before tightening any hardware.
2. Drive the stakes using a rubber mallet, alternating between front and back pegs to keep the anchor tight against the leg frame. For screw-in anchors, rotate clockwise until the top ring meets the ground.
3. Secure the straps at every leg — never tether to a single point, which creates a pivot that amplifies wind leverage. Attach ratchet straps from multiple legs, crisscrossing under the frame for balanced hold.
4. Remove the safety net and mat before forecasted storms above 50 mph. The net acts as a sail, multiplying wind force by roughly 30%. Without the fabric surface, the frame alone is far less likely to lift.

Periodically check anchors after heavy rain or freeze-thaw cycles — soil loosens over time, and a previously secure anchor can develop play. Avoid mowing over top of them.

Common Mistakes That Cause Anchors to Fail

Using nylon webbing is the most frequent error — it stretches far enough under sudden gusts that the trampoline lifts several inches before the strap stops it. By that point, the frame may already be tilted or flipped. Stick to polyester ratchet straps rated for the full load.

Tethering to only one leg creates a pivot point, letting the frame spin and lift unevenly. Always connect straps to every leg, or at minimum between every other leg, with the lines pulling in opposite directions. Sandbags alone are not enough for hurricane-force winds — they shift and spill when the trampoline begins to lift, leaving nothing behind to stop it.

FAQs

Can I leave the net on during moderate wind?

No. The safety net acts as a fabric wall that catches wind like a sail, dramatically increasing the force on the frame. Remove the net and mat before any storm with sustained winds over 35 mph, even if the trampoline is anchored.

Do I need a separate anchor kit for a jumbo trampoline?

Yes. Jumbo frames — 16 feet and larger — have more surface area and generate greater lift. A standard four-anchor kit is insufficient; you need a double kit with eight anchor points or an equivalent number of high-rated screw stakes to distribute the wind load.

How often should I recheck the anchors after installation?

Inspect after every heavy rain, snowmelt, or freeze-thaw cycle. Soil compaction changes with moisture, and a tight anchor can loosen as the ground shifts. A quick tug at each leg reveals any play before the next storm hits.
