The Irish Climate

Ireland's climate is temperate. Given Ireland's high latitude the weather is quite mild. Temperatures rarely fall below freezing point in winter, but might sometimes due to easterly winds. Irish summers may be considered good if the temperature rises above 16 degrees Celsius, though some parts of the country routinely have higher temperatures and 30 degrees is nothing new.

  • The dominant influence on Ireland's climate is the Atlantic Ocean.
  • Average annual temperature is about 9 °C.
  • In the middle and east of the country temperatures tend to be somewhat more extreme than in other parts of the country.
  • Mean annual windspeed varies between about 4 m/sec in the east midlands and 7 m/sec in the northwest.
  • Strong winds tend to be more frequent in winter than in summer.
  • Sunshine duration is highest in the southeast of the country.
  • Average rainfall varies between about 800 and 2,800mm.
  • With southwesterly winds from the Atlantic dominating, rainfall figures are highest in the northwest, west and southwest of the country, especially over the higher ground.
  • Rainfall accumulation tends to be highest in winter and lowest in early summer.
  • The annual number of days with more than 1 mm of rain varies between about 150 in the drier parts and over 200 in the wetter parts of the country.
The best way to prepare for Irish weather is to make sure you have warm clothes, at least one waterproof coat, some strong shoes, warm blankets and bedding.

To study effectively, it is important to keep the rooms that you work in warm enough.
