Many parts of the country experienced their wettest July for more than 50 years, Met Eireann said today.
The worst of the summer washout hit Leinster and Munster with some areas suffering three times the usual rainfall for the month.
The rest of the country fared little better as twice the usual levels of rain were dumped.
Met Eireann said Atlantic depressions tracking over Ireland were to blame for the wet weather and frequent thunderstorms, repeating the pattern of the last two summers.
But despite the heavy rain, there was some consolation for sun seekers - sunshine levels were generally above normal, with many days having bright mornings and early afternoons before the showers developed.
The worst of the weather saw dramatic flooding at the beginning of July, when homes were evacuated and commuters left stranded after thunderstorms tore through eastern and western parts of the country.
In Newport, Co Mayo, 42mm of rain lashed down in a one-hour spell on Thursday July 2 – a once in 150-year event.
On the same day, Dublin Airport recorded 42mm of rain – its wettest on record for July.
Overall, the capital’s 122mm rain total for the month was its highest since 1936.
The Valentia Observatory in Co Kerry had its wettest July since records began in the area in 1866, with 256mm of rain measured, while Johnstown Castle in Co Wexford had almost four times its normal July downpour.
The North West managed to escape the worst of the washout, however, with just 72mm – the lowest rainfall total for the month – measured at Malin Head.
Temperatures showed little variation and were near or slightly above average for July.
