Climate and Weather of Ireland

Located not far from England, Scotland and Wales, Ireland is a place to avoid if one are not fond of rain. With reason, because the island - also known as the Emerald Isle - is characterized by its humidity, with no less than 250 days of rain per year!

However, thanks to the moisture, the country has such beautiful and wild landscapes. Moreover, these rainer days present an opportunity to admire the beautiful rainbows in the sky, as these are common on Irish soil!

In Ireland, one will literally be faced with all types of rain: the small drizzle, the big drops of rain - the choice is yours. On a more positive note, the climate in Ireland is not limited to this humidity! The country has, just as its English neighbor, a wide variety of climates and everything can change in just a few hours. Generally, the rains are short enough and alternate constantly with beautiful sunshine at times, just as with their Normandy neighbours. The wettest area of the island is located in the southwest mountains, while the eastern coast is much drier, especially towards Dublin.

Fortunately, the high humidity climate of Ireland also knows very mild temperatures, with pleasant winters and hot summers that are more than bearable. Moreover, whether one is in Dublin or in Birr, the country presents very little temperature differences. Do not get too accustomed to the warmth! Other places like in London, Edinburgh, Ireland and its capital, Dublin, can still be surprised by snowfall occasionally throughout winter.
