Malin Headrecorded 29 rain days – in contrast to 14 such days at Phoenix Park, Co Dublin.
A rain day is a day on which 0.2mm or more of rainfall is measured.
Forecaster Paul Moore said the location where a person lives has a huge bearing on what type of weather is experienced “even in a small country like Ireland”.

Highlighting a “big disparity” between the northwest and southeast, he said: “The climate trend of warmer and wetter summers is continuing when it comes to comparing the data over two 30-year periods of weather information.
“There is a lot more moisture in the air when there is low pressure and that low pressure positioned itself over the north and northwest but petered out once it got to the east and southeast.”
Last month was the 35th warmest since the national forecaster started recording temperatures 125 years ago.
Overall the average temperature reached 15.5 degrees for the entire month. The temperature is 0.20 degrees above the most recent 1991-2020 long-term average (LTA), 0.28 degrees above the period from 1981 to 2020 and 0.79 degrees above the years 1961 to 1990 for August.
Provisional rainfall data for Ireland suggests August this saw 114 per cent or 117 millimetres of its 1981-2010 long term average rainfall and 113 per cent from 1991 and 2020.
When it comes to rainfall, it was the wettest in the northwest and driest in the east and south. Percentage of 1981-2010 LTA rainfall values were variable across the country.
