According to the forecaster, the cities with the greatest rain in 2019 were Athenry and Galway. Met Eireann announced in its 2019 Preliminary Climate Summary that Athenry was the wettest place in Ireland, with 120 percent of the usual annual rainfall. Galway came in second, with 115 percent.
Athenry lies in west-central County Clare. It's a small town of about 1,500 people on the R541 road between Ennis and Limerick. The city's name comes from the Irish atain ri mban meaning "oak tree river bank." In English, it's sometimes called Atina River Bank because of this feature of the local landscape.
The average yearly temperature in Athenry is 10 degrees Celsius (50 degrees Fahrenheit). The coldest month is January, with an average temperature of 3 degrees Celsius (37 degrees F); the hottest is July, with an average temperature of 17 degrees Celsius (63 degrees F).
Galway is a large coastal city in western Ireland on the Atlantic Ocean. It is also the capital of Galway County. With more than 100,000 residents, it is Ireland's third most populous city after Dublin and Belfast. Galway is located near the mouth of the Galway River, which flows into Galway Bay. The city center is situated on a peninsula between Galway Bay and Galway River.
Dublin is the driest place in Ireland, with less than 800 mm of rain per year. *Excludes Rockall Island, which is located in the north Atlantic 440 kilometers northwest of Donegal. The island is a United Kingdom territory and lies between the North Atlantic Ocean and the Arctic Sea.
Rockall Island has no surface water at all. The only moisture to reach it comes from the Gulf Stream and other ocean currents that carry precipitation across the continent.
The average rainfall on Rockall Island is less than 6 inches (150 millimeters) per year. It is so dry that there are no freshwater lakes or rivers on the island.
However, since it is isolated and completely covered by grasslands and shrubs, some areas receive more rain than others. For example, the northeast region receives about 40 inches (1 meter) of rain per year while the southwest gets only about 8 inches (20 centimeters).
Rockall Island was originally part of the country of Denmark but was transferred to the United Kingdom in 1953 after being claimed by both countries.
Since then, the island has been used for grazing livestock and hunting wild birds. It is also a major staging point for seabirds migrating between Europe and North America.
Rainfall is quite prevalent in Ireland. December and January are the wettest months practically everywhere. In general, April is the driest month, however in many southern areas, June is the driest. The most rainfall occurs between October and March.
The table below shows the average monthly rainfall in different parts of Ireland:
Location Average monthly rainfall (inches)
Ireland overall 40-60
West of Ireland 70-90
East of Ireland 90-110
South Coast 100-120
Great Island of Ireland 95-115
Great Britain overall 45-65
Northern Ireland 40-60
Lough Neagh 120-140
Lough Erne 140-160
The city is located in the least wet portion of Ireland's island, because some of the moisture from the ocean is released on the west side as rain, yet rain is common in Dublin, but it is rarely excessive. The average annual rainfall is around 60 inches (1,500 mm), with more than half of that falling between April and October.
Dublin has a temperate climate, with warm to hot summers and cold, dry winters. It is not unusual for temperatures to rise above 100 degrees F (38 degrees C) during the summer months, but a large proportion of those days are overcast or rainy, so it rarely gets too hot.
There are two main reasons why Dublin is often wet: its location on the Atlantic Ocean means it is exposed to the winds which come in from the water, and the ground is flat which means any moisture that does get held in the soil will be able to drain away quickly.
Dublin has a number of small lakes and loughs that appear after storms when the tide goes out. These usually go unnoticed by most people because they do not stay open long enough for anyone to swim in them, but they do provide habitat for many birds and animals. For example, one such body of water called Lough Neagh is important for wildlife in Eastern Ireland.
