Rainfall increased by 7% in those years with the north and west seeing the biggest rise.
Ireland has become warmer, wetter and sunnier over the last 30 years, according to a new summary by Met Éireann of the changes to the country's climate from 1991 to 2020.
The average air temperature in Ireland over the 30 years up to 2020 was 9.8C - which is 0.7C higher than the previous 30-year period up to 1990 and the rise in temperature was observed across all four seasons.
Rainfall also increased by 7% in those years with the north and west seeing the biggest rise. While the east of the country was wetter, it was not to the same extent.
There was also more sunshine with an average of 63 more hours of sunshine per year - a 5% increase.
May was the sunniest month and the month which saw the greatest temperature increase - an average of one degree.

December was the dullest month, while October saw the lowest mean temperature rise - just 0.2 Celsius.
Winter and autumn were the wettest seasons with spring the driest.
Met Éireann said these changes are consistent with previously published projections for how climate change will impact Ireland.
