Where should you go in Ireland in january when it comes to the weather?

Remember:
The climate in Ireland in january ranges from bad to very bad depending on the region and city.

As the month of January is at the heart of the winter season, expect the weather in Ireland throughout January to be characterized by rainy and cold days. Even though temperatures rarely drop below zero, most Irish cities face cool temperatures and showers that can occur at any time of the day.

The Irish East Coast throughout January

The climatic conditions of the Irish east coast are relatively mild compared to those of the rest of the country. In fact, the rains are rare and give way to the beautiful sunny days that count many. However in order to feel comfortable, do not forget to dress warmly because the temperatures remain around 7° C, even at the best of the day.

Northern and Western Ireland throughout January

With temperatures ranging between 6° C and 8° C, cold days dominate the weather in Ireland throughout January - although snow is rare. On the other hand, it is to be expected that relatively heavy rains will occur especially in the early morning or afternoon. If one combines the sunny days with the cloudy ones, there is plenty of time for outdoor activities.

Central Ireland throughout January

The prevalence of rainfall in the center of the country is lower than in the north. This is reflected in the dominance of the fine weather - even if the cloud coverings are not to be excluded. On the other hand, the cold is more accentuated, with minimum temperatures around 3° C and maximum temperatures that hardly exceed 6° C.

South West Ireland throughout January

It is in the south of the country that the climate throughout January in Ireland is the mildest, even if temperatures remain below 10° C - one can take advantage of the presence of the sun, thanks to the absence of the rains that have remained rare under the influence of the Gulf Stream.
