what is the average temperature in autumn & Winter in Ireland ?

Answer 1

Autumn is not too bad (mildish 12-18C). It starts getting darker, damper and colder in late October, early November. December still can be mild some days, just dark (daylight from 8:30am to 3:45pm). Nevertheless, prepare for cold, wet weather (the coldest would be about -2C). I think February is the coldest month. We had some nights that were -7C.

Answer 2

early autumn the temperatures are about 18 degrees
late autumn the temperature is about 12 degrees
winter is about 7 or 8 if your lucky
