Irish public data, by county
StatsMapped

Rainfall for every Irish county, ranked from highest to lowest, from official public data.

Why the caveats matter

Every figure carries the publisher's own caveats. Where a statistic is published for a wider area than the one you clicked, or where the publisher itself flags it as unreliable, the page says so rather than quietly rounding it off.

Two or more areas with the same figure share a rank -- the next rank is skipped (e.g. two areas tied for 1st means the next entry is ranked 3rd, not 2nd).

Before you use these figures

  • One station's own reading, not a county-wide average: This figure comes from a single rain gauge, not an average across the county. Rainfall varies genuinely by location — especially across larger or more mountainous counties — so parts of the county may see more or less rain than this station's own reading.
  • Station chosen for continuity, not central location: The station shown for each county was chosen for having the longest unbroken current record among that county's currently-reporting rain gauges, not for being centrally located or most representative.
  • A volunteer network, not automated sensors: Most of these stations are read manually by volunteer observers, not automated instruments — Met Éireann's own long-running Cooperative Climate Network. Occasional gaps in an otherwise long record usually reflect a period with no observer, not missing rain.
