For years, Wyoming has held the title of the windiest state in the US, thanks to its rugged terrain and powerful gusts, County 10 reports.
However, new data from World Population Review reveals a shift in rankings, with Wyoming now trailing behind two other states in terms of average wind speed.
Over the past 12 months, Wyoming recorded an average wind speed of 20.9 mph, placing it just behind Montana (21 mph) and the new leader, South Dakota (21.3 mph). Despite this slight drop in ranking, Wyoming remains among the windiest places in the country, with gusts that continue to shape daily life for its residents.
Other states rounding out the top five include Idaho and Colorado, reinforcing the influence of the Rocky Mountain region on wind activity. Meanwhile, the least windy state in 2025 was Delaware, with an average wind speed of 12.9 mph, followed by California, Louisiana, Connecticut, and Hawaii.
Meteorologist Don Day previously explained Wyoming’s windy nature in a 2023 Cowboy State Daily report, attributing it to the state’s unique geography. Unlike other mountainous states, Wyoming has large gaps between its mountain ranges, creating natural wind funnels that accelerate airflow across the region.
While Wyoming may have lost its top ranking, strong winds remain a defining feature of life in the Cowboy State. Residents are still adapting to gusty conditions, with local experts and even real estate professionals offering lighthearted tips on how to cope with the ever-present breezes.
