Ireland, though located fairly far north, is situated on the Gulf Stream, which keeps the country from experiencing the extreme temperature differences that other locations at the same latitude do.  During the summer months, the average temperature in Galway is around 68 degrees F, while in the winter the temperature averages around 34 degrees F.  Galway, as with all of Ireland, does get quite a bit of rainfall.  The rain is heaviest in the winter months, but can be heavy at any time.  For an up to date forecast of Galway's weather click here .
