Hi, I am planning to visit Dublin over the next 2 weeks and i am aware that the weather can change drastically within a day. The average reported temperature is about 17 deg Celsius but I am just wondering if how cold would it feel like due to wind and rain etc. I live in Singapore and experience summer throughout the year, hence I know i'm intolerant to cold. Is it advisable to bring a thick and heavy winter jacket or will i thin down jacket be sufficient? Thank you and much appreciated!!
