Mike, I've only checked the figures for Aldergrove. NI did not share in the long sequence of extremely low night minima in Jan 1982, so that Dec/Jan was marginally less cold. However, Dec/Jan 78-9 was colder at Aldergrove. I've not checked 95-96 or 96-97. 2009-10 2.8°C 1981-82 3.0°C 1978-79 2.4°C It's just possible, I suppose, that the regional NI figure was the same as or slightly lower this year than in 78-79, but a similar figure should suggest that some parts of Ulster were higher and some were lower, which would not excuse the dogmatic "lowest for 47 years" ... at least for anyone with half a brain :-) Thanks so much for that. I hade a look through the data from my station, 1968 to 2002, and spotted something I always seem to forget. The same period in 1976/77 had a mean here of only 2.7C. I then contacted Mark Bailey at Armagh Observatory (obs started around 210 years ago) and he kindly gave me the figures for there. 1962 Dec 4.5 1963 Jan 0.0 1976 Dec 1.8 1977 Jan 2.3 1978 Dec 4.3 1979 Jan 0.8 2009 Dec 3.0 2010 Jan 2.0 So not only was 76/77 a good deal colder than recently, it was in fact colder than in the same two months in 62/63! That was a real surprise. I wonder what Aldergrove was in 76/77? -- Mike Tullett - Coleraine 55.13°N 6.69°W posted 2/2/2010 1:01:17 PM GMT |

I was working in Aberdeen during the 76-77 winter and remember December especially as very snowy (checking the MWR reveals 21 days with snow lying at Dyce in Dec and 11 in Jan (probably mostly in the first half). Braemar had 28 and 26 respectively. I agree with Martin's figures for Aldergrove, but it is worth pointing out this his source and my source (MWR) all pre-1984 data refers to 12h day max and night min rather than 24h max and 24h min. My data for this winter is also 12h maxes and mins. I've also checked the 1976-77 figures for Dyce (0.6 degC lower than this winter), Eskdalemuir (same as this winter), Lerwick (0.8degC lower than this winter), and Stornoway (also 0.8 degC lower than this winter). Curiouser and curiouser. Philip |

There seems no doubt this has not been the coldest Dec/Jan, though it may have been the second coldest for some of us, particularly in the central lowlands area. I'll echo your thanks to Philip and Martin. Alex. |

Mike, I haven't looked up any figures but my recollection is that 1962/63 wasn't anything like as cold in NI as it was in England & Wales. NI was much like SW Scotland that winter. I was commuting 30 miles each way between Largs and Prestwick Airport by motorbike that winter and it wasn't too bad. NI did have a notable blizzard, in Feb I think. The same blizzard affected the extreme SW of Scotland but didn't extend as far north as Prestwick. -- Norman Lynagh Tideswell, Derbyshire 303m a.s.l. |

Although I wasn't around during the 1939/40 winter the local folklore in Largs, Ayrshire where I was brought up was that 1940 was the big daddy of winters there in the 20th century. I have seen photos of the snow that winter and in terms of total depth and drifting it was certainly much greater than anything in 1947 or 1963 -- Norman Lynagh Tideswell, Derbyshire 303m a.s.l. |
