Storms: Mitigating Wind & Hail Impact

A practical guide for reducing storm-related damage on Northern Adelaide Plains farms.

Why Wind & Hail Risk Matters

Severe storms—especially hail and high winds—are becoming more common in the Northern Adelaide Plains. For local growers, this can mean sudden crop loss, damaged infrastructure, and safety concerns. But with the right planning, these risks can be managed and reduced.

Key Regional Risks

Hailstorms damaging vulnerable crops like tomatoes and cucumbers

Strong winds ripping plastic coverings from tunnels or greenhouses

Safety hazards for workers caught in storm conditions

Sheds or structures collapsing during storm events

Prevention & Preparedness

Simple steps to strengthen your farm’s resilience before disaster strike

  • Hail netting acts as a physical shield, significantly reducing crop loss from hail impact. According to AIDR, protective structures like netting are one of the most cost-effective ways to mitigate damage to fruit and vegetable crops during hailstorms.

  • Proper anchoring prevents wind uplift and structural collapse—common causes of damage during severe wind events. Reinforced frames provide greater stability, reducing the risk of entire greenhouses being torn apart.

  • Loose materials can become dangerous projectiles in high winds, damaging infrastructure or injuring workers. Securing these items limits both physical and economic damage during a storm.

  • Tree lines and hedgerows reduce wind speed and turbulence across paddocks. These natural barriers can shield crops and infrastructure from the full force of a storm and help control erosion post-event.

  • Over time, fastenings can weaken, especially in high-use areas. Regular checks help ensure that coverings stay in place during storms, preventing tears, flapping, and detachment that expose crops or infrastructure to further damage.

After the Storm make sure you:

  • Remove debris and inspect for structural damage immediately

  • Prioritise crop areas for insurance assessments

  • Notify supply chain contacts of any delays or disruptions

  • Replace torn netting or plastic coverings quickly to avoid further damage
