Rain is rarely the real enemy. The damage comes from what rain leaves behind: water pooled on a tabletop, a damp cushion that never dries, or a cover that traps moisture against the frame for a week. If you are wondering how to protect outdoor furniture from rain, the good news is that a few habits do most of the work, and none of them require buying a whole new set.
I have seen a good wooden bench ruined in one wet season because it sat under a plastic tarp that held humidity like a greenhouse. I have also seen a ten-year-old aluminum set stay perfect with a breathable cover and a ten-second shake-off after storms.
Protection depends on three things: the material, the cover, and drainage. Get those right and rain stops being a problem.
This article is general information. Always check your furniture maker’s care instructions, since sealants and cleaners differ by material. It covers a quick answer, a material table, a cover comparison, a before-and-after-rain routine, mistakes to avoid, and a short FAQ.
How can you protect outdoor furniture from rain?
To protect outdoor furniture from rain, use breathable, waterproof covers that fit snugly, store cushions indoors or in a dry box, apply a sealant that suits the material, lift furniture off wet ground with pads or feet, and remove pooled water quickly. Clean mildew early, and avoid plastic tarps that trap moisture.
What does each material need?
| Material | Rain risk | What helps |
|---|---|---|
| Teak, cedar, eucalyptus | Natural oils repel water and resist rot | Regular teak sealant keeps the golden color |
| Softwood or untreated wood | Water absorption causes swelling, warping, and rot | Seal only when the wood is bone-dry and the maker allows it |
| Aluminum and stainless steel | Resistant to rust and corrosion | Minimal care, but moisture can damage the finish |
| Wrought iron and steel | Rust | Primer plus outdoor metal paint or clear rust-preventative spray |
| Natural wicker and rattan | Should never be left exposed to direct rain | Keep under cover |
| Resin and plastic | Decent, but can develop mildew in shaded areas if not cleaned | Clean regularly |
| Fabric cushions | Hold water for days | Remove and store indoors or in a dry deck box before rain |
Which cover works best?
| Cover type | Result |
|---|---|
| Fitted, breathable, waterproof | Repels rain while letting trapped humidity escape |
| Cheap plastic tarp | Traps moisture and creates a humid, greenhouse effect that speeds mold and rust |
| Loose cover | Strong winds can lift loose covers and expose furniture |
| Pooled water on cover | Remove it promptly from the depressed tops of covers |
Choose a cover that fits snugly, with ties or straps to resist wind.
What should you do before and after rain?
| When | Task |
|---|---|
| Before rain | Move cushions inside, cover furniture, tilt chairs forward so water runs off |
| During a heavy storm | Move lightweight pieces under a porch, or into a shed |
| After rain | Shake off covers, wipe tabletops, dry hardware |
| Within a day | Check joints, fasteners, and covers for damage after high winds or heavy rain |
| Weekly in wet seasons | Check for mildew, rust spots, and peeling finish |
| Seasonally | Reapply sealant or protector as the product directs |
Elevating furniture off the ground cuts moisture creep. Protective pads or feet help keep water from seeping in through the legs.
How do you deal with mildew?
| Step | Action |
|---|---|
| 1 | Tackle early signs like fabric discoloration, bubbling paint, or a musty smell |
| 2 | Wipe with mild soap and water |
| 3 | Use diluted vinegar or a specialty cleaner if needed |
| 4 | Avoid harsh cleaners that can strip protective finishes |
| 5 | Avoid pressure washing softwoods or wicker |
| 6 | Let everything dry fully before covering |
What mistakes should you avoid?
- Sealing damp wood. Moisture gets trapped inside.
- Using plastic sheeting. It traps condensation underneath.
- Leaving cushions out. They stay wet for days and grow mildew.
- Ignoring water pooling. Tilt or elevate pieces so water drains.
Frequently asked questions
Should you cover outdoor furniture in the rain?

How do you dry wet cushions?
Stand them upright in the shade with good airflow, then store them dry.
Bottom line
Match your protection to your material, use breathable fitted covers, store cushions, and keep furniture off wet ground. Dry everything after storms, and clean mildew early.
