NATIONAL BIG WIND DAY
Observed each year in the United States on April 12th, National Big Wind Day commemorates the recording of the highest natural wind gust measured on the Earth’s surface. On the afternoon of April 12, 1934, the Mount Washington Observatory recorded winds at 231 miles per hour.
Mount Washington is the highest peak in the Northeastern United States at 6,288 ft, and it is the most prominent mountain east of the Mississippi River.
Observers Wendell Stephenson, Alexander McKenzie and Salvadore Pagliuca reported the wind gusts in 1934 from the Mount Washington Observatory. The record even held for several decades. In 1984, the observers returned to the observatory to celebrate the record-breaking wind’s 50th anniversary. Then in 1996, the big wind award from atop Mount Washington fell. A typhoon struck a small island off of Australia with wind gusts of 256 mph.
