Kilkeel in Co. Down recorded a gust of 124 mph (108 knots) on 12th January 1974, the highest recorded gust in Northern Ireland (see http://www.metoffice...te/uk/extremes/
); thus the speeds given at Claremorris, etc, above, may also be around 12th.
P.K. Rohan's 1986 book "The Climate of Ireland" states on page 139) that "A storm which passed to the north-west of the country on the night of 11th-12th gave widespread gales, and record speeds were reported from a number of locations.....At Kilkeel in Co. Down winds reached a speed of 55.6 m/s (108 kt) in gusts, the highest recorded for a station at sea level in Ireland. A storm on the night of 27th-28th also did widespread damage particularly in the west of the country."
It also refers to Table 55 on page 145 which list maximum gusts recorded at 17 stations (2 in Clare, 2 in Cork, 1 in Donegal, 2 in Dublin, 1 in Kerry, 1 in Kilkenny, 1 in Limerick, 3 in Mayo, 1 in Monaghan, 1 in Offaly, 1 in Westmeath and 1 in Wexford). These values range from 75 knots (c. 86 mph) at Dublin Airport on 12th January 1974 to 98 knots (c. 113 mph) at Malin Head, Co. Donegal, on 16th September 1961; Foynes Island, Co. Limerick, also recorded an estimated value of 98 knots on 18th January 1945 but the exact value is not known as the instrument went beyond the upper edge fo the scale; Claremorris, Co. Mayo, also recorded a gust of 97 knots (c. 112 mph) on 27th January 1974. and Quilty, Co. Clare, recorded an estimated 97 knots on 27th January 1920, but as with Foynes on 18.1.1945 the instrument went above the upper end of the scale. Other months mentioned in this table are 4th February 1957 (91 knots or c. 105 mph at Roche's Point, Co. Cork), 22nd October 1961 (87 knots or c. 100 mph at Rosslare, Co. Wexford, 14th January 1968 (86 knots or c. 99 mph at Glenamoy, Co. Mayo) and 13th December 1981 (81 knots or c. 93 mph at Casement Aerodrome, Co. Dublin). The periods covered vary from the period from 3rd January 1911 to 31st January 1961 at Quilty, Co. Clare to the period from 1st February 1967 to 31st December 1984 at Casement Aerodrome, Co. Dublin; Roche's Point, Co. Cork, had a break between 2 periods of 1st March 1905 to 8th January 1914, and 1st December 1955 to 31st December 1984); apart from Quilty, Roche's Point, and Foynes Island whose period of record ended on 31st May 1946, records generally went up to 31st December 1984.
Page 139 also states that a gust of 65 m/s (126 knots, or c. 145 mph) was recorded on an anemometer at the top of a television mast near the top of Kippure Mountain, Co. Wicklow, at an altitude of 754 metres or c. 2,474 feet above sea level) on 14th January 1968 when gusts of about 36 m/s (70 knots or c. 81 mph) were occurring at Casement Aerodrome, which is about 94 metres (c. 308 feet) above sea level and some 18 km. (c. 11 miles) away. The ratio on this occasion was approximately 1.8 to 1. Thus one might possibly expect gusts of c. 194 knots (c. 223 mph) to have occurred near the tops of the Mourne Mountains (which rise to 2,796 feet or c. 852 metres) when the gust of 108 knots (c. 124 mph) occurred at Kilkeel on 12th January 1974. This is actually well ahead of the highest wind speed recorded even at a high level station in Britain, of 173 mph on 20th March 1986 at Cairngorm Mountain (1245 m. or c. 4084 feet) in Scotland (see http://www.personal....er_in_march.htm
). The highest gust at a low level station in Britain is 123 knots (c. 142 mph) at Fraserburgh, Aberdeenshire, on 13th February 1989 (see http://www.metoffice...te/uk/extremes/
Table 56 on page 146 gives maximum recorded 10 minute average wind speeds recorded for each month, during the period 1st January 1940 to 21st December 1984 inclusive. Thse vary from 21.6 m/s (c. 42 knots or c. 48 mph) at Shannon Airport (Foynes) on 12th July 1943, to 36.6 m/s (c. 71 knots or c. 82 mph) also at Shannon Airport (Foynes) on 18th January 1945.
