Dublin Weather Guide

Along the east coast of Ireland and in particular Dublin, the climate is significantly better than other parts of the small country. It’s a known fact that rain is very much present all year round in Dublin, however during the months of April through to August the sun shines predominantly and only light sprinkles of rain may push through every so often. Whatever time of year you decide to visit the Irish capital, be sure to bring clothing that can be layered, a waterproof jacket and some sturdy shoes.

Season and Clothing

Winter: November to March

Winter in Dublin is chilly, although temps hardly ever drop below the freezing mark. This time of year becomes busy around Christmas as shoppers hit the high streets in a frenzy and cosy pubs light up open wood fires and sell Guinness by the barrel load. The amount of rain that falls each month ranges between 75 millimetres in December to 50 millimetres in March as the winter season draws to a close. Be sure to check out the St Patrick’s Day Festival in the city, which runs annually from March 17 for up to 5 days to celebrate Dublin’s patron saint.

Average temperatures:  3 – 10 degrees Celsius.
Appropriate clothing: Warm winter layers, thermals, a scarf, a waterproof coat, thick jumper and sturdy shoes.
Don't forget: A beanie, gloves and an umbrella!

Spring: April to May

The spring season is impressive in Dublin as the plants in the area have received a thorough drenching of rain over the past months promoting huge growth and natural colours that beam brightly, almost making the precipitation worthwhile. April generally sees the least rainfall with an average of 47 millimetres making this month ideal for checking out the Georgian architecture and beautifully manicured gardens of Dublin’s squares.

Average temperatures:  5 – 15 degrees Celsius.
Appropriate clothing: Warm layers, a beanie and a coat.
Don't forget: An umbrella and sunglasses.

Summer: June to August

Summertime in Dublin sees the capital generally turn on nice weather that includes extended daylight of up to 17 hours making for longer days to get out and about to explore the city or enjoy the well-lit ambience at night. It’s not unusual for it to rain at some point during the day; however these instances are typically scattered showers that last up to a few hours at a time.

Average temperatures:  10 – 20 degrees Celsius.
Appropriate clothing: Casual layers including pants and a jacket for night.
Don't forget:  A hat, sunscreen and sunglasses.

Autumn: September to October
