The highest recorded non-tornadic wind speed is 253 mph, which was recorded during the tropical cyclone Olivia, a category 4 cyclone, at Barrow Island, Australia on April 10, 1996. The record was officially confirmed by the World Meteorological Organization in 2010, 14 years after it was recorded.
The previous world record for highest wind speed of 231 mph was recorded at Mount Washington in New Hampshire. It was recorded in April 1931. A Doppler weather radar recorded a wind gust with a speed of 318 mph in 1999 during an F5 tornado in Oklahoma City. However, records by Doppler radar are not considered official.
