Highest wind speed

Ground Level Wind speed Location Date
mph km/h knots
Low level (up to 500 m) 142 228 123 Fraserburgh, Aberdeenshire 13 February 1989
High level (above 500 m) 173 278 150 Cairn Gorm, Scottish Highlands 20 March 1986

Shetland holds the unofficial British record for wind speed. A gust of 197 mph (317 km/h) was reported on 1 January 1992. An earlier gust in 1962 was recorded at 177 mph (285 km/h), both at RAF Saxa Vord.[12] However, it is expected that higher gusts than those reported would have been achieved as during both storms the measuring equipment was destroyed by the extreme weather.[13]

A wind gust of 194 mph (312 km/h) was recorded at Cairn Gorm on 19 December 2008 but was discovered too late to be verified by the Met Office.[14]
