- Fifty-five people were killed during a violent snowstorm on Valentine's Day in in 1853 when the Queen Victoria ship struck rocks off Howth Head, Dublin
- In 1886, before systematic records began, a blizzard with snow up to 60cm deep is said to have struck Northern Ireland.
- The early part of 1947 was recorded as one of the most persistent cold spells of the century, with people reported to be skating on frozen ponds in February.
- Dublin airport saw 10 consecutive days of snow in February 1955.
- The winter of 1963 was the coldest of the 20th century, the forecaster said, as a large Scandinavian anticyclone brought easterly winds over Ireland.
