When the heat hits, it hits fast—and your animals feel it before you do. If you’re asking how to protect your livestock during extreme summer weather, this checklist walks you through everything you need to prepare for a heatwave.
Why Heatwaves Are Dangerous for Livestock
Cattle and other large animals generate internal heat from digestion, and when outdoor temperatures spike, the barn environment can quickly become harmful. Without proper airflow and cooling, animals are at risk for heat stress, reduced feed intake, and serious health issues.
Your Summer Heatwave Prep Checklist
1. Test Every Fan
Before the heatwave arrives, take a walk through the barn and test every fan individually. Many facilities have fans that were installed but never wired in—or quietly stopped working without notice.
- Turn each fan on manually
- Confirm it runs at full speed
- Check for weak airflow—inspect belts and pulleys if fans are slow
2. Clean Motors and Blades
Dust and debris don’t just reduce airflow—they can also cause overheating, especially in barns where moisture levels are high. Clean fans are more efficient and safer.
- Blow dirt off motors using compressed air
- Wipe blades and cooling fins
- Keep fans clean to maximize airflow
3. Scan With a Thermal Camera
Thermal imaging helps detect problems that aren’t visible during normal checks. Spotting an overheating contactor or breaker early can prevent a full system failure during a heatwave.
- Check breakers, relays, and fan motors for heat buildup
- Identify failing components before they stop working
4. Inspect Soakers, Misters, and Foggers
If you rely on additional cooling tools like misters or soakers, verify that they’re in working order before the heatwave hits.
- Clear clogged nozzles
- Check hoses for leaks
- Soak misting tips in vinegar if you have hard water buildup
5. Verify Curtain and Tunnel Ventilation
Tunnel ventilation is only effective if everything moves in sync. Make sure the system is ready to handle rising temperatures without any delays or malfunctions.
- Ensure vents and curtains open fully
- Sync fan and curtain operation
- Remove any airflow obstructions
6. Automate Where You Can
A ventilation controller can take pressure off your team during hot weather. Automated systems adjust fans and curtains based on real-time data, providing faster, more reliable responses.
- Use a ventilation controller to start fans and open curtains at preset temperatures
- Respond to heat in real time without constant oversight
7. Use HVLS Fans for Large-Area Cooling
HVLS fans are highly effective in wide, open layouts like bedded pack barns. They create gentle but powerful airflow that cools large spaces quietly and efficiently.
- Ideal for bedded pack barns and open layouts
- Spread airflow across large spaces
- Reduce bedding needs and improve air quality
Final Takeaway
Preparing for a heatwave starts long before the temperature rises. Routine checks, cleaning, and airflow optimization can make a big difference in how your animals handle the stress of extreme heat. If you’re unsure how to set up your barn’s airflow system for maximum impact, AmeriWind can help. We’ve worked in thousands of barns—and we know what keeps them cool, safe, and productive.
