A national steam rally, an airshow and an outdoor music festival were among the casualties of heavy rain in many parts of the country over the bank holiday weekend.
There were also reports that Kildare's senior hurlers were delayed arriving at Croke Park for the Christy Ring Cup final because their team bus encountered flooding.
Elsewhere, AA Roadwatch said motorists were experiencing flooding on the Tramore road in Waterford.
Gardaí said that traffic dispersing out of Dublin following yesterday's GAA matches in Croke Park was busy, but manageable.
Among the areas worst affected by rain were parts of Munster, Leinster and the midlands, but the west appeared to have escaped the most severe downpours.
Met Éireann's station at the Casement aerodrome in Baldonnel recorded the heaviest rain, with 46mm (1.81 inches) falling between 6pm on Friday and 6pm last night.
Stations at Roche's Point in Cork, Cork airport and Mullingar in Co Westmeath also recorded between 37mm and 43mm of rain.
By comparison, Malin Head recorded just 4.2mm of rain, while Belmullet recorded 7.9mm.
Not everyone will earn a respite from the rain today, however.
According to Met Éireann's Jim O'Brien, while it will be bright with some sunny spells, there will also be heavy, thundery showers.
"The showers in some places will be far worse than others . . . All areas are at risk, but not everyone will get them," he said.
The organisers of yesterday's National Steam Rally at Stradbally, Co Laois, did not need telling it was a very wet weekend.
It was among several events, including an airshow that was part of Bray's Summerfest and the Farmleigh Affair music festival in the Phoenix Park, to be cancelled yesterday.
The airshow in Bray has been rescheduled for September 2nd.
