Climate Of Ireland

climate and weather forecast IrelandThe Atlantic Ocean exerts a considerable influence on the climate of Ireland and this can be seen in the fact that Ireland enjoys a rather moderate climate, which is much unlike other countries that lie at similar latitudes.

However, although the overall temperature tends to be moderate, the eastern and central areas of the country do tend to experience more climactic extremes and have more of a temperature range than coastal areas do. While the average annual temperature is approximately 9°C, the temperatures in the eastern and central areas tend to fall outside this average with 19°C being the mean summer daily maximum and 2.5°C being the mean winter daily minimum.

Ireland is a fairly wet country with the average rainfall totalling between about 800 and 2,800mm of precipitation annually. Moreover, because Ireland’s climate is affected most by south-westerly winds coming from the Atlantic Ocean, the areas of the country which get the most rainfall tend to lie in the western end of the country. The western, north western and south western areas as well as the more mountainous areas of the country tend to get the most precipitation.

Ireland tends to have a fairly wet climate, giving rise to the nickname “The Emerald Isle”. A look at the number of days of rain in which more than 1mm of rain shows that drier parts of the country tend to get around 150 days of rain. More precipitation-heavy areas of the country can receive as many as 200 days of rain. The data from weather stations is collected by Met Éireann. They have collected data which dates back to the nineteenth century.

The chart below indicates the average annual temperature for the station at Malin Head. It is expressed as the departure from the normal temperature in degrees Celsius and covers the period from 1961 to 1990. The black line on the graph represents the average of a 15 year period which is centred on the year in question.
