Average Annual Precipitation for Ireland

The tables below give yearly averages for rainfall plus snowfall at major cities and other places around Ireland.

Each location has a total for how many days of wet weather it usually gets a year and for the normal amount of precipitation.

The calculation of days only includes the days when precipitation totalled at least 0.2 millimetres (0.008 inches). For Donegal and Galway, the total days includes any with at least 0.1 mm (0.004 inches) of precipitation.

The annual amounts of rain and snow given here are averages of weather data collected during 1981 to 2010.

Munster province covers the southern part of Ireland. Leinster province is in the east, while Connacht (or Connaught) is in the west.
