Autumn was warmer than average with new data from Met Eireann saying that Dublin temperatures were 0.6 degrees higher than usual.
November was also warmer and wetter, with some parts of the country experiencing the wettest month in six years.
Other parts of the country recorded their wettest days in 47 years, while Storm Barney's high winds caused disruption in the west.
The south of the country, however, was exceptionally dry in October with only 40pc of the average rainfall recorded.
However, the data shows that November saw more than double the average rainfall in some parts of the country.
Met Eireann Weather Forecaster Joanna Donnelly said that while climate change is a global issue, it is not possible to say if the changeable weather can be blamed on global warming.
"It is a global phenomenon that needs to be looked at globally over decades and not days," she said.
"Our climate is changing but you could not use the weather in any one country in any one month, day or year to say that this is the evidence of climate change," she added.
"Climate change is evident all over the globe all of the time."
The weather station at Johnstown Castle, Co Wexford, recorded its driest autumn for eight years, with only 73 pc of the long-term average amount of rain falling there.
Mullingar had the warmest temperature in autumn, with the mercury rising to 20.3 degrees in Westmeath on September 10.
However, the following day was the wettest autumn day since 1968.
Mayo got the brunt of the wet weather. The station at Newport recorded 79.4mm of rainfall on September 11 and later went on to record the wettest November day for 47 years.
More than 320mm of rain fell there in November, making it the wettest November month since 2009.
While it was a particularly warm month, rainfall was well above average in most parts of the country.
The midlands were also badly hit, with Mullingar recording more than double the average amount of rainfall for November. Shannon Airport's weather station recorded its wettest autumn in five years with 20pc more rain than average.
Dublin was dry in comparison with the Casement Aerodrome recording autumn's lowest rainfall with 180.5mm.
The effects of Storm Barney saw wind speeds reach highs of 128 km/h at Shannon Airport.
This forced one plane to abort two attempts to land at Shannon before diverting to Liverpool.
Valentia Observatory in Kerry recorded the month's highest temperature on November 1 at 19.5 degrees.
Only three days of frost were recorded throughout the month across the country. Dublin had the month's coldest temperature with a reading of -2.7 degrees.
Ms Donnelly said that the mixed weather is likely to continue into the beginning of December.
"For the next few days we are going to have a few cold days and nights ahead of us before milder air pushes up from the south again," she said.
