People pack for Dublin like it's cold. It mostly isn't. Highs run 8°C (46°F) to 20°C (68°F) all year, and the real problem is rain that turns up on 10 to 19 days every month, so a waterproof layer matters more than a heavy coat.

Season by season
Winter
December–FebruaryHighs sit between 8°C (46°F) and 10°C (50°F) and lows between 4°C (39°F) and 6°C (43°F), with rain on 11 to 14 days a month. It's damp more than freezing, and the wind off the bay on the Howth cliff walk or along the Liffey makes it feel colder. Bring a warm mid-layer under a waterproof shell rather than one bulky coat.
Spring
March–MayMarch is wet, with 16 rain days and an 11°C (52°F) high. By May it's 16°C (61°F) with 10 rain days, the driest month of the year. Layers are the answer here: a t-shirt, a sweater and a shell will cover a sunny morning in St Stephen's Green and a soaked afternoon.
Summer
June–AugustSummer is mild at 18°C (64°F) to 20°C (68°F), and nights stay around 12°C (54°F) to 13°C (55°F). Don't expect it to be dry. July is the wettest month at 19 rain days, so the shell stays in your bag even in peak season.
Autumn
September–NovemberSeptember holds on at 17°C (63°F), October drops to 14°C (57°F) and November to 11°C (52°F), with 14 to 16 rain days a month. Days get short fast. Pack a sweater, a waterproof and shoes that can handle wet pavement.
What to bring to Dublin
0 of 20 packedDublin gets rain on 10 to 19 days every month, and a waterproof shell that packs into its own pocket beats an umbrella the wind will wreck.
For him, the same idea: it squashes into its own pocket, so it's in your bag when the sunny morning in Phoenix Park turns wet.

What shoes should you pack for Dublin?
Bring shoes that cope with wet pavement and cobbles. Temple Bar's lanes and Trinity College's Front Square are cobbled and slick after rain, and most visitors cover the center on foot. Water-resistant walking shoes beat knit sneakers here, because knit soaks through in the first shower.
What do people wear in Dublin?
Dubliners dress casually: jeans, a sweater, a rain jacket and decent shoes. Pubs, even the nicer ones, don't need anything smarter than that. A dark, neutral jacket fits in better than a bright hiking shell if you're heading out at night.
What plugs does Dublin use?
Ireland uses type G, the same three-pin plug as the UK, at 230V. US, EU and Australian travelers need an adapter. Most phone and laptop chargers handle 230V fine, but check hair tools.

What should you leave at home for Dublin?
Leave the big umbrella. The wind turns it inside out on O'Connell Bridge and a hooded shell does the job better. Leave the shorts too, unless you're very optimistic about July.
