By the first week of June in Melbourne, the alfresco stops being a room and starts being weather. The dining table gets rained on four days out of seven. By the August long weekend the timber has gone grey and blotchy, with a green film creeping along the chair rails. A well-chosen outdoor table cover is the cheapest insurance you can buy against that season — but only if it fits properly and you use it the right way.
This guide is written for the southern states: Victoria, Tasmania, South Australia and the cooler pockets of NSW, where winter is not simply cold but persistently damp. We look at what a cover has to do, why ventilation matters more than waterproofing, how timber behaves through a wet season, and when to shift furniture under a roof instead. The full range sits in our outdoor furniture covers collection.
What an outdoor table cover has to do in a wet winter
A northern-Australian summer storm is a short, violent event. A southern winter is the opposite: weeks of low sun, high humidity and drizzle that never quite dries off. Your cover is not fighting one downpour. It is holding a line against months of moisture that wants to sit in every joint and screw hole.
Shedding water off the top matters, but so does staying put in a Bass Strait southerly, and so does letting trapped air escape. Water that gets underneath and cannot get out does more damage than rain falling on bare timber.
Covers are sold by setting size rather than table dimensions, which trips people up. A seven-piece setting means a table plus six chairs, so the Cover 7pc Dining Setting ($110) is the usual starting point for a six-seater. An eight-seater steps up to the Cover 9pc Dining Setting ($125). We have already worked through the piece-count maths in our guide to outdoor furniture covers by setting size, so this post stays on the wet-season problem instead.
Ventilation, not waterproofing, is what stops mould
The most common winter complaint we hear is not a soaked table. It is a table that comes out from under its cover in September looking worse than the one next door that stayed uncovered. That is almost always a ventilation problem.
Warm air rises off a tabletop during the day and condenses against the inside of the cover overnight. With nowhere to go, that moisture drips back down, and a sealed, dark, damp space is where mould and mildew want to live. Air vents exist for this reason, and blocking them with a tarp defeats the design.
Three habits make the difference. Never cover a wet setting — wipe the top down and give it an hour of moving air first. Do not weigh the hem to the ground with bricks all the way around. And on a dry, breezy day, pull the cover off for a few hours.
Timber tables through a cold, wet season
Timber rewards a bit of planning in June. Teak, kwila and other dense hardwoods handle rain far better than people expect, and the silvering that shows up over a wet winter is a change in colour rather than damage. What causes real trouble is a mould bloom left to sit for three months.
Give the table a proper clean before the cover goes on for the season: warm water, a soft brush, and a rinse with the grain rather than across it. Let it dry completely. Resist the urge to oil timber on the way into winter — oil applied to damp timber in a cold month can seal moisture in and go patchy, so spring is the better window. Solid pieces like the Teak Dining Tables (from $697) and the rest of our outdoor dining tables range are built to weather.
Where your setting sits changes the answer
Look honestly at where the table lives. The same setting needs very different treatment on an exposed Hobart deck than under a roofed alfresco in Adelaide.
| Where it sits | Best approach | Watch out for |
|---|---|---|
| Fully exposed deck or lawn | Fitted cover on for the season, checked monthly | Water pooling on the tabletop; you need tie-downs for wind |
| Under eaves or a pergola | Cover the table, stack chairs uncovered | Wind-driven rain from the open side; legs stand in run-off |
| Roofed alfresco | Often no cover at all — regular wipe-downs | Damp, still air; a cover can trap more than it keeps out |
| Garage, shed or under the house | Move smaller tables and folding chairs inside | Needs a dry, ventilated spot, not flat against cold concrete |
Larger settings rarely have anywhere to go. A ten-seater is a two-person lift, and most households do not have a spare garage bay. For those, the Cover 11pc Dining Setting ($139) is the pragmatic answer: the setting stays where it is, and it stays covered.
A June-to-August routine for VIC, TAS and SA
Southern winters are not identical. Hobart and Launceston get frost and long stretches where nothing dries. Melbourne's real enemy is humidity off Port Phillip paired with wind that lifts anything loose. In the Adelaide Hills and around Ballarat, overnight frost followed by morning sun means repeated freeze and thaw.
Work to a simple rhythm. Late May: deep clean, dry completely, fit the cover. Mid-winter: a monthly check on a dry day, lifting the cover to look for pooling or mould spots. Early September: cover off, wash down, and oil the timber if you are going to. Apartment dwellers should check their body corporate or strata by-laws before securing anything to a balcony rail, as these vary building to building.
Fit decides whether any of this works. A cover that is too big billows and acts like a sail; one that is too tight will not seat over the chair backs and tears at the seams. If you are unsure which size to order, our guide to outdoor furniture covers that actually fit walks through measuring your setting first.
Outdoor table covers — frequently asked questions
Should I cover my outdoor table in winter or move it inside?
Cover it where it stands if the setting is large or the table is solid timber built for outdoors. Moving furniture into a garage only helps when that space is dry and ventilated. Smaller tables and folding chairs are the exception.
Why does my outdoor furniture go mouldy under its cover?
Trapped moisture with nowhere to escape is the cause, nearly every time. Either the setting was covered while still wet, or the vents are blocked and condensation is cycling inside.
Do I need to oil a timber outdoor table before winter?
No — spring is the better time. Oil needs dry timber and mild conditions to soak in evenly, and applying it in a cold, damp month risks a patchy finish. Clean and dry the table before winter instead.
What size outdoor table cover do I need?
Match the cover to your setting's piece count, not the table measurements alone. A six-seater is generally a seven-piece cover and an eight-seater a nine-piece. A round table needs a round cover rather than a rectangular one pulled over the top.
Shop the range
If your table is round, start with the Cover 9pc Round Setting ($142). A rectangular cover stretched over a round setting leaves gaps at the corners and pools water in the middle. Browse the rest of the covers range alongside our outdoor dining settings before the wet months set in. We deliver Australia-wide with free delivery on orders over $100, and most orders are dispatched in 3-10 business days.
