Dublin Weather in December

Updated: 13 octubre 2023

This post covers the weather to expect in Dublin in December and during Christmas.

At this time of year, the weather in Dublin tends to be cold, wet, and a bit windy but with several nice days.

As a retired meteorologist turned tour guide, I didn't expect that I would use my experience as a forecaster in my new career in tourism.

But here I am, finding myself answering more weather questions as a blogger than I ever did as a weatherman.

So, here are answers to some frequently asked questions about the weather in Dublin in December.

What to Wear?

December is cold so bring along winter attire including jeans or other heavy trousers.

Take along long-sleeved tops and shirts, hoodies, and a warm and preferably waterproof coat.  

A couple of scarves, some gloves, and warm socks will also help. Don’t forget some good walking shoes.
