At night time Ireland has been consistently the warmest country in Europe throughout this Winter, with night time temperatures close to 10C on many nights. Only recently has places like Greece and southern Spain joined Ireland with mild night time temperatures.
This may not be the mildest winter of all time, but it's certainly in my top 3 list of mild winters since the 1970s in terms of mild daytime and nighttime temperatures, almost complete absence of snow and very little frost.
In case of your curiosity, I have created the following analysis for Dunsany based on temperature data of previous Winters (means are based on midnight to midnight readings rather than 0900 to 0900 UTC readings).
Winter (December to February) mean temperatures, mean max and mean min temperatures.
Keep in mind, some or all data is not available for the following Winters: 1967-68, 1970-71, 1971-72, 1979-80, 1984-85, 1991-92, 2007-08. So beware of the sudden down spikes as a result in points of the graph.
Coldest: 2009-10 with a mean of 2.2c
Mildest: 1988-89 & 1997-98 with a mean of 6.4c
2018-19 up to January is currently running at 6.3c. Mean minimum is currently record high at 4.0c but one more month of data to consider.
