When autumn arrives, many inflatable paddleboards get packed away until spring. The problem isn't a cold garage by itself: it is putting a wet, salty, tightly folded board into storage, then opening it months later to find mould, discoloured material or creases that have become difficult to manage.
Here is our practical winter-storage checklist for UK inflatable SUPs, including whether to leave your board inflated, what to do with the valve, and how to get it ready for the first spring paddle.
Quick answer: how should I store an inflatable paddleboard?
- Wash off salt, sand and dirt with fresh water.
- Allow the board and fittings to dry fully, including seams, deck pad and fin box.
- Check for damage, loose fittings or slow leaks before storing.
- Store inflated at reduced pressure if you have enough suitable space, or loosely rolled if you do not.
- Keep it away from prolonged UV, heat sources, pests, sharp edges and standing water.
- Follow the valve and pressure recommendations in your specific board manual.
Inflated or deflated: which is best over winter?
Either can work if done correctly. If you have a clean, dry storage space, leaving the board inflated below normal paddling pressure reduces folding and makes it easy to inspect. It should never be left at full operating pressure near a heat source or where temperature rises could increase internal pressure.
If space is limited, deflate and roll the board loosely according to its manufacturer's instructions. Avoid leaving it tightly compressed for months with the fin, leash or hard objects digging into the material. A bag is for protection, not a reason to crush the board into its smallest possible package.
Can I store my paddleboard in a cold garage?
A cool dry garage can be fine. Dampness, condensation, pests and heat fluctuations are more important concerns than low temperature alone. Don't leave a board sitting directly in standing water or against a heater. Avoid handling and unfolding PVC aggressively when it is exceptionally cold and stiff; allow the board to warm gradually before setup.
Should I leave the inflation valve open?
Follow the board manufacturer's storage instructions. In general the valve mechanism should remain clean, protected and free of trapped grit. Do not leave a cap off where insects, dust or moisture can get in; equally, do not force or overtighten a valve. The correct stem position varies by valve design and whether the board is stored inflated or rolled.
How to prevent mould and smells
The main defence is drying thoroughly before packing. Pay attention to the foam deck pad, carry handles, luggage bungees and seams. Wash with products approved for your board's materials rather than aggressive solvents. If you notice mould, clean it promptly using the manufacturer's approved guidance and dry again before repacking.
What should I do with my fin, leash and paddle?
Remove detachable fins, rinse and dry the fin box and store fins where they cannot crack or bend. Rinse the leash and check its cord, swivel and attachment points for wear. Separate adjustable paddle sections, wash away salt and dry them so they do not seize together. Check locks and clamps before packing away.
Should I repair a small leak before winter?
Ideally yes: an undiagnosed leak is frustrating to discover at the start of the season. Check the valve carefully before assuming a seam or board-body failure. Use the repair approach approved by your board manufacturer, and seek proper assessment for seam separation, large damaged areas or structural faults.
Spring restart checklist
- Unroll and inspect the board in a clean space.
- Inspect fin box, handles, rails and valve before full inflation.
- Inflate to the board's specified operating pressure and check for leaks.
- Reinstall and check the fin, leash and paddle clamps.
- Inspect your buoyancy aid, clothing and weather forecast before launching.
UK winter paddling: storing isn't the only choice
Some paddlers keep using their SUP all winter. That can be rewarding, but cold water, wind, reduced daylight and getting back to shore matter more than summer equipment care. For clothing and safety start with our UK wetsuit buying guide and winter paddling guide. Never rely on a wetsuit alone as a substitute for planning, suitable buoyancy and a safe return route.
Useful maintenance kit
Browse care accessories and SUP accessories for suitable storage, cleaning and repair items. Only use cleaners, adhesives and lubricants recommended for your board materials and fittings; different constructions can need different care.
FAQs
Can I leave an inflatable SUP inflated all winter?
Often yes, in a suitable indoor storage area and at reduced pressure, subject to the manufacturer's instructions. Check periodically for changes in temperature and pressure.
Will storing a SUP rolled up damage it?
Not if it is completely dry and rolled appropriately, but prolonged tight compression or trapped hard objects can create problems.
Is freezing weather bad for an inflatable paddleboard?
Cold makes materials less flexible. Avoid flexing or unfolding a very cold board, and protect it from damp, abrasion and sudden heat.
Should I put talcum powder on the board?
Not as a general rule. Follow the manufacturer's material-specific care instructions rather than adding substances unnecessarily.
