The term Hibernophile may conjure an image of someone who enjoys settling in for a long winter’s nap. In fact, Hibernophiles are fans of Hibernia, the classical Latin name for Ireland.
The name is said to have originated from Greek descriptions of the land; the Alexandrian polymath Ptolemy called the island Iouernia in his cartographic book Geographia. The Romans likely picked up on the similarity between this Greek form of the name and the Latin word hibernus, meaning wintry. (Think “hibernate” and “hibernacle.”) Hibernia may be interpreted as the “land of winter,” or with some poetic license, “the island of the eternal winter.”
The MODIS (Moderate Resolution Imaging Spectroradiometer) on NASA’s Aqua satellite captured this hibernal image on January 19, 2023. On that day, clouds had mostly cleared after an Arctic air mass brought hail, sleet, snow, and frost to the island. Snow clings to areas of higher elevations.
In Ireland, snow falls most frequently in January and February, according to the Irish Meteorological Service, though flurries can fly from November through April. The coatings of white tend to be fleeting, and many winters go by without a major snowstorm. However, more extreme wintry weather does occasionally strike. For example, frigid Arctic air ushered in an early winter in 2010. And in more distant history, a huge snowfall in the year 764 reportedly stuck around for three months.
On the whole, though, Ireland experiences a moderate climate thanks to the North Atlantic Drift Current which carries warm ocean waters to higher latitudes. The water around the island tends to be coldest in February and March, leading to a slow warmup of air temperatures in the spring—and perhaps giving the impression that winters will never end.
While winters may not always bring much snow, they do tend to be windy. In the lead-up to the winter of 2023‐2024, persistent winds delivered a green energy victory to the Emerald Isle. On December 6, 2023, Ireland reached an all-time high for wind power output on the country’s grid: Wind met over 70 percent of Ireland’s electricity demands for that day. Ireland ranks among the top countries in the world in terms of the proportion of wind power in its electricity generation mix. In 2022, wind accounted for one-third of its energy production.
