What type of rain gear should I take to Ireland?

Where have you people been living?? it never stops raining especially during summer, it rained for 64 days straight last summer that was some kinda record, and apparently we are in for another wet one this summer, however there has hardly been rain this winter , but it's so bloody cold out! Anyhow, umberella all the way, most people use them, you can get away with a light fol up rain jacket aswell, something you can roll up in your bag. in the summer last year the rain was very heavy, my house was flooded, so it wasnt light summer rain. but we can have 4 seasons in a day, i dont think you'll be prepared no matter what.
