When is the best time to go to Ireland?
The slightly difficult climatic conditions in Ireland are most certainly not a reason to miss out on the great opportunities to have fun and discover the architectural heritage that is otherwise described in fairytales. The many festivities that take place in Ireland throughout the entire year attract those who like to party. The best time to travel to Ireland and enjoy the sun is undoubtedly the summer season: June, July and August. During these months, tourists flock to Ireland in order to enjoy the mild climate. Spring marks the beginning of cultural events, as with the Six Nations when all rugby fans turn their attention to Ireland. Then, the month of March brings St. Patrick's, a festival that enchants the whole territory; the jubilant crowds amuse the streets for 5 days in order to celebrate the patron saint of Ireland. Autumn is cool enough and this period is suitable for art and theater enthusiasts. Some travelers choose to visit Ireland during the winter, but only to relax in peace because with all the rain, outdoor excursions are pretty much out of the question.

Climate and Weather in 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.
