When There Is Strong Wind, Should You Close or Open Your Windows? Many People Are Getting This Wrong

When strong winds pick up, many homeowners instinctively react without thinking twice—some rush to open windows to “equalize pressure,” while others tightly shut everything in sight. Surprisingly, a large number of people are doing the wrong thing, and the right answer depends on one key factor: safety.

The Common Myth: Opening Windows Reduces Pressure

A widely believed idea is that opening windows during strong winds or storms helps reduce pressure inside the house and prevents damage. This may sound logical, but in reality, it often causes more harm than good. Open windows allow wind to enter the home, increasing internal pressure and placing extra stress on the structure—especially on the roof.

The Correct Approach: Close and Secure

In most cases, windows should be closed during strong winds. Keeping them shut prevents gusts from rushing inside and reduces the risk of sudden pressure buildup. Wind entering through open windows can lift roofs, slam doors, shatter glass, and turn loose objects into dangerous projectiles inside your home.

When Open Windows Become a Risk

Strong winds can:

• Slam windows shut unexpectedly, breaking glass
• Pull debris into the home
• Increase internal pressure, stressing walls and ceilings
• Cause interior damage from airborne objects

Even a slightly open window can act like a wind tunnel, allowing gusts to build force rapidly.

What About Ventilation?

Ventilation is important, but strong winds are not the time for it. Mechanical ventilation systems, exhaust fans, or HVAC units are far safer options when airflow is needed. Natural ventilation through open windows should be reserved for calm or mild weather conditions.

Exceptions to the Rule

There are very limited scenarios—such as specific industrial buildings or engineered ventilation systems—where controlled airflow is designed to handle high winds. Typical residential homes are not built for this, making open windows unsafe during windy conditions.

Additional Safety Tips During High Winds

• Secure loose outdoor furniture and objects
• Lock windows and doors to prevent sudden openings
• Close curtains or blinds to reduce glass shatter risk
• Stay away from windows during peak wind activity

The Bottom Line

During strong winds, closing your windows is the safest and smartest choice. The idea that opening them helps protect your home is outdated and incorrect for most modern houses. By keeping windows shut and secured, you reduce structural stress, prevent damage, and protect everyone inside.

When the wind dies down, then it’s safe to let the fresh air back in.
