Winter in the UK brings cold temperatures, high humidity, and limited daylight—all of which can shorten the lifespan of inflatable paddle boards if they are not stored correctly.

For rental operators, tour companies, clubs, and private owners, proper winter storage is not just about saving space. It is about preventing mold, valve damage, seam failure, and material fatigue before the next paddling season begins.

This guide explains how to store inflatable paddle boards during winter in the UK, based on industry standards, climate data, and real-world manufacturing experience.

Why Winter Storage Is Especially Important in the UK

The UK’s maritime climate creates unique challenges for inflatable SUPs:

• Average winter humidity: 80–90% (UK Met Office)

• Frequent temperature fluctuations: 0–10°C

• Condensation risk in garages, sheds, and storage units

According to RNLI safety guidance, moisture trapped inside water sports equipment during storage is a leading cause of long-term material degradation and mold growth.

For businesses managing multiple boards, poor winter storage often leads to:

• Mold under EVA deck pads

• Corrosion inside valves

• Micro-cracks in PVC seams

• Higher repair and replacement costs before spring

Step 1: Clean Thoroughly Before Storage

Before storing any inflatable paddle board, cleaning is essential.

Best Practice:

• Rinse the board with fresh water to remove salt, sand, and organic debris

• Use a mild soap (no solvents or harsh detergents)

• Pay special attention to:

  • Valve area

  • D-rings

  • Deck pad edges

  • Fin boxes

💡 Why this matters:
Organic residue combined with UK humidity creates the ideal environment for mold spores to grow during storage.

Step 2: Dry Completely — Inside and Out

This is the most commonly skipped step and the biggest cause of winter damage.

Recommended Drying Process:

1. Inflate the board to 3–5 PSI

2. Leave it in a well-ventilated indoor space

3. Allow at least 24–48 hours to dry fully

4. Open the valve briefly to release trapped internal moisture

According to material testing data from inflatable watercraft manufacturers, even a small amount of internal moisture can cause mildew within 2–3 weeks in high-humidity environments.

Step 3: Deflate Correctly (Avoid Over-Folding)

Once dry:

• Deflate slowly

• Fold loosely from the nose toward the valve

• Avoid sharp creases, especially in cold conditions

❄️ Cold PVC becomes less flexible, increasing the risk of stress marks or micro-fractures if folded tightly.

Tip for rental businesses:
Rotate fold lines each season to reduce repeated stress on the same areas.

Step 4: Choose the Right Storage Location

Ideal Winter Storage Conditions in the UK:

• Temperature: 5–20°C

• Dry, ventilated environment

• Away from direct sunlight

• No exposure to frost or condensation

Avoid:

• Damp garages

• Outdoor sheds without insulation

• Unheated shipping containers

• Attics with large temperature swings

According to the British Marine Federation, controlled indoor storage significantly reduces long-term degradation of inflatable marine equipment.

Step 5: Store Inflated or Deflated?

For most UK rental businesses, fully deflated storage is the safest and most practical option.

Step 6: Protect Valves, Accessories & Leashes

Before storage:

• Ensure valves are fully closed

• Remove fins

• Detach leashes and dry separately

• Store repair kits in sealed bags

A report by SUPBoarder Magazine UK found that valve-related issues account for over 30% of post-winter repair requests, most caused by moisture exposure.

Common Winter Storage Mistakes in the UK

❌ Storing boards while slightly damp
❌ Leaving boards in freezing conditions
❌ Tight folding during cold weather
❌ Storing near heaters or boilers
❌ Ignoring internal moisture

Winter Storage Checklist (UK Climate)

✔ Clean with fresh water
✔ Dry for 24–48 hours
✔ Release internal moisture
✔ Fold loosely
✔ Store indoors, dry & ventilated
✔ Protect valves and accessories

A Note for Rental & Tour Businesses

Winter is not just a storage period—it’s a planning season.

Many UK rental operators use the off-season to:

• Assess board condition

• Replace aging fleets

• Upgrade materials or widths

• Prepare branded boards for next season

From a manufacturing perspective, off-season ordering allows better customization, more stable lead times, and improved cost control.
