If you're planning anything outdoors in Limerick, the city is the cloudiest in Ireland — only around 1,295 sunshine hours a year, with 62 days a year recording no measurable sunshine at all. The trade-off is genuinely mild winters thanks to the Gulf Stream and the Shannon Estuary, with snow rare and frost limited to a handful of days. The Shannon itself shapes the city in a different way: parts of central Limerick are flood-prone, and river-related weather concerns matter here in ways they don't in inland Irish cities.
