Should You Leave Your Windows Open When Away in Sioux Falls? What to Know

At BHGRE® Beyond, we know that homeownership in Sioux Falls comes with unique considerations—from the region’s dramatic weather to local security dynamics. While the idea of coming home to fresh air is appealing, leaving your windows open when you’re not there can pose risks that outweigh the benefits. Here’s what you need to know to make an informed decision for your Sioux Falls home.


The Risks of Leaving Windows Open in Sioux Falls

Weather Risks

Sioux Falls experiences severe summer storms in spring, summer, and fall, with threats including excess rain, thunderstorms, lightning, hail, tornadoes, and high winds. Damaging wind gusts can reach up to 60–70 mph, and hailstones can exceed 2 inches in diameter. High winds can dislodge siding, lift shingles, and even damage windows, while sudden rain can lead to water intrusion, mold growth, and structural damage. Leaving windows open during these conditions can expose your home to costly repairs and safety hazards.

Security Risks

While Sioux Falls has a lower violent crime rate than the national average, property crimes such as theft and vandalism do occur. Leaving windows open—even on upper floors—can provide an easy entry point for intruders. As the city grows, so does the likelihood of increased crime, making it important to prioritize home security. Modern security systems with cameras and motion sensors can help, but the simplest precaution is to keep windows closed and locked when you’re away.

Energy Efficiency and Pest Control

Leaving windows open can also lead to energy loss, as heated or cooled air escapes and outdoor air enters uncontrolled. This can strain your HVAC system and increase utility costs. Additionally, open windows can invite pests like insects or small animals into your home, which is especially concerning during warmer months.


When It Might Be Safe to Leave Windows Open

There are rare instances where leaving a window cracked might be acceptable in Sioux Falls:

  • Screened Windows on Upper Floors: If you have secure, screened windows on an upper floor and live in a low-crime neighborhood, leaving them slightly open for ventilation may pose minimal risk. However, this is only advisable in calm weather and for short periods.
  • Controlled Ventilation: If you’re using window stops or locks that limit how far a window can open, you can allow some airflow without fully exposing your home. Always ensure these devices are properly installed and maintained.

Precautions If You Choose to Leave Windows Open

If you decide to leave your windows open while away, take these steps to minimize risks:

For Weather Protection

  • Check the Forecast: Always review the latest weather updates from the National Weather Service Sioux Falls before leaving windows open. Severe weather can develop quickly, and being caught off guard can lead to significant damage.
  • Install Window Stops: Use devices that limit how far a window can open, reducing the risk of wind or rain entering while still allowing some airflow.
  • Secure Screens: Ensure all window screens are in good condition and properly secured to prevent pests and debris from entering.

For Security

  • Use Window Locks: Install locks that allow windows to be slightly open but prevent them from being fully opened from the outside.
  • Invest in a Security System: Consider a system with motion sensors, cameras, and real-time alerts. Local providers like FOSS Security offer solutions tailored to Sioux Falls homes, including real-time monitoring and theft prevention.
  • Neighborhood Awareness: If you’re in a close-knit community, ask a trusted neighbor to keep an eye on your home. However, don’t rely solely on this—always take physical precautions as well.

For Energy Efficiency

  • Use Window Fans or Ventilation Systems: Instead of leaving windows wide open, consider using fans or smart ventilation systems that can circulate air without compromising security or energy efficiency.
  • Close Windows During Extreme Temperatures: In the middle of winter or during heatwaves, keep windows closed to maintain indoor climate control and reduce HVAC strain.

Local Insight: Sioux Falls’ Unique Considerations

Sioux Falls’ climate and security landscape require homeowners to be especially mindful of their decisions. The city’s frequent severe weather—including hail, high winds, and storms—means that leaving windows open can quickly turn a small oversight into a major headache. Additionally, while property crime is a concern, taking simple precautions like closing and locking windows can significantly reduce your risk.

For homeowners who value fresh air, consider alternatives like energy-efficient ventilation systems or smart home technology that allows you to monitor and control your home’s environment remotely. These solutions provide the benefits of airflow without the risks.


The Bottom Line

In most cases, it’s not advisable to leave your windows open when you’re not home in Sioux Falls. The risks—ranging from weather damage to security vulnerabilities—generally outweigh the benefits. If you do choose to leave windows open, take every precaution to protect your home from the elements, pests, and potential intruders.
