Is 20 mph Wind Strong? Everyday Impacts and Safety

Wind strength is often assessed using objective scales that describe its observed effects. These classifications provide a consistent way to categorize wind speeds, helping understand their influence on daily activities and the environment.

Understanding Wind Strength

A 20 mph wind is classified as a “Fresh Breeze,” corresponding to Force 5 on the Beaufort Wind Scale. This scale categorizes wind speeds based on their observable effects on land and sea. At this strength, small trees with leaves sway noticeably. On larger bodies of water, moderate waves develop, and many whitecaps become visible, sometimes accompanied by spray.

To provide context, a “Moderate Breeze” (Force 4) ranges from 13 to 18 mph, raising dust and moving small tree branches. In contrast, a “Strong Breeze” (Force 6) is between 25 and 31 mph, characterized by large tree branches moving and whistling sounds in overhead wires. Therefore, 20 mph sits at the upper end of a fresh breeze, indicating a noticeable wind generally below the threshold for significant disruption or damage.

Everyday Impacts of 20 mph Wind

A 20 mph wind can have several noticeable effects on daily life and outdoor activities. When walking or cycling, individuals will likely experience significant resistance, requiring increased effort to move against the wind. This level of wind can make outdoor activities challenging, as objects like picnic blankets or lightweight gear may be difficult to secure. The trajectory of thrown or hit balls in sports can also be significantly altered, affecting play.

The wind’s force is often apparent on outdoor objects. Light patio furniture, such as plastic chairs or small tables, may shift or even blow over if not secured. Trash cans, especially empty ones, can be tipped by the wind. Small tree branches will sway consistently, and loose items like leaves and paper on the ground will be lifted and carried by the breeze. For drivers, particularly those in high-sided vehicles like vans or trucks, a 20 mph crosswind can create a slight but persistent pull on the steering wheel, requiring active correction to maintain a straight path.

Safety and Practical Considerations

Given the characteristics of a 20 mph wind, certain practical measures can enhance safety and minimize inconvenience. It is advisable to secure any loose outdoor items, such as garden tools, lightweight decorations, or children’s toys, to prevent them from being moved or damaged. For those near bodies of water, understanding that 20 mph winds create choppier conditions with whitecaps is necessary for boating or waterside activities.

Gardeners should consider protecting delicate plants, especially new growth or taller, less sturdy varieties, as swaying can cause stress or breakage. Dressing in layers and wearing wind-resistant outerwear can help stay comfortable when spending time outdoors in these conditions. Checking weather forecasts before engaging in outdoor plans allows for preparation and adjustment to activities, ensuring a more pleasant and safe experience.
