This week will bring more normal conditions for the time of year following on from a near record-breaking September heatwave.
The heatwave, only the fourth in recorded history for September in Ireland, ended on Sunday with heavy rain and thunderstorms.
The highest temperature last week was a 28.5 degrees recorded at Oak Park in Co Carlow on Friday. A heatwave is defined in Ireland as five successive days where the temperature is above 25 degrees.
There was flash flooding in many parts of the country on Sunday.
