Dublin Weather

Dublin has a very temperate climate, with no true temperature extremes. It is considerably warmer than most areas of its latitude because it’s in the north-eastern Atlantic Ocean and its climate is governed by the North Atlantic Current. It is described as a moist, mild and changeable climate with abundant rainfall. Tornadoes, thunderstorms, and other violent phenomena of nature are rare. Additionally, the same current that keeps the island country mild, also keeps the coastline of Ireland ice-free throughout the winter.

The Pleasant Time to Visit Dublin

Snuggled into a cove in the middle of eastern coastal Ireland, Dublin has some of the warmest temperatures in the country. The last two weeks of April and the month of August usually has its most pleasant weather, with average temperatures ranging between 25.8 and 31.5 C. August is an energetic month for Dubliners, with World Cup rugby warm up games and an enthusiasm for karaoke nights and other live entertainment.

While March is full of crazy St. Paddy’s Day celebrations in and around Dublin, April in comparison is a more relaxed month. The cheerful spring month begins with the Great Ireland run and progresses into the Clautarf Viking Festival. It’s also the time when they have the Dublin Bay Pawn Festival, with fantastic opportunities for tasting Irish prawns. April is generally the driest month, although sometimes June or July competes for those days of sparkling sunshine.

Cloudy with a Chance of Rain

It’s true that it rains a lot in Ireland, and you can expect rain on any day of the year, but it doesn’t mean there will be a season of torrential downpours. As May moves in, the temperatures remain balmy, with average temperatures of 28.4 C. It may feel muggy as the day is often overcast, but the rain is sporadic, from soft, light rains to occasional drizzling rain. Dublin is retrieving its daylight hours quickly in May, clocking an additional three minutes a day, with the earliest sunrise on May 31, at 5:03 AM, and the sun settling down on the horizon at 8:55 PM.

May is an excellent time to visit Dublin if you wish to beat the crowds, but weren’t able to arrange your holiday for an earlier date. You can expect one of those rare, completely clear, golden days nine percent of the time, a mostly clear day thirteen percent of the time, and a mostly cloudy day, thirty-nine percent of the time. That’s not enough to bring out the sun screen, but it is enough for enjoying plenty of outdoor activities.

June and July is the peak of tourist season, and may be the reason why Ireland has a reputation for a rainy climate. Your chances of a completely clear day drop down to six percent, while the odds that it won’t rain are less than one in two.

However, if you’re a writer, there can be no better time to visit Dublin than in June. Throughout the month, there are writer’s festivals held at various venues. High on the list is the annual Writer’s Festival, drawing over fifty well-known poets and writers from all over the world. The Programmes are highly explorative, with selective readings from heavyweights like Julian Barnes read back to back with the innovative approach of Arabic contemporary poetry.

The Bloomsday Festival takes place June 16 at the James Joyce Centre. Taking the name from the central figure of Joyce’s “Ulysses”, the weeklong festival is a celebration of the renowned contemporary author, and comes complete with readings of Joyce, performances, excursions and meals to help set the mood for 1904 Dublin. In order to ensure a part in the festivities, it’s strongly advised you book your reservations in advance.

While daylight hours are still at a height in June, the sun has begun retreating by July. The 5:01 AM sunrise that greeted the emerald city on July first, waits until 5:39 AM to climb over the horizon. It has begun losing daylight by 2.4 minutes from the beginning to the end of July.

When it’s Time to Dress in Layers

Autumn can have somewhat unpredictable weather in Dublin. Although typically it begins cooling off by late August, recent years have seen some surprisingly warm weather in September, with temperatures averaging 19 C and running as high as 24 degrees C. For those who are used to cooler climes, this is shorts and t-shirts weather, but don’t leave behind your sweaters and fleece. If a northerly wind blows in, it will be chilly and those exposed knees will get goose bumps. The best thing to do is hope for the heat, but prepare for the cold. Keep some light clothing packed in your gear, but carry along sweaters, slacks, a jacket and warm shoes.

By October, you’re definitely starting to feel the weather change. The average temperature is 11 degrees C., with lows plummeting to 8 degrees C. Your chances of rainy weather are high, with an average of twenty-four days of rain out of the month, and your chances don’t improve for November. You will want to take your layered clothing more seriously, and boots are the most practical apparel for your feet. Your umbrella will be your best friend, and your chances of seeing a snow day are boosted to seven percent.

Frost is very common during the winter months, but snow is sporadic. Depending on how cold it has been throughout the winter months, you may or may not see snow accumulation. Snowfalls can occur anytime between October and early May.

Winter is generally when you can get your best rates for airline travel, hotel accommodations and dining. However, you will want to research your choices ahead of time because many hotels and restaurants close during the late winter months.

Dublin has numerous winter festivals, with activities that include ice skating, dizzying rides and a winter carnival. Dubliners are very lavish during the winter holiday season, decking out the town with lights, Christmas trees, decorations and reminders of the festive season with fireworks. You will find a lively artisans Christmas market, a Santa train, and the Square Shopping Centre’s Christmas market. While the fun never stops, the Christmas season can be the most expensive time for planning a holiday.

When visiting Dublin, prepare for rain no matter what time of the year you are planning your holiday. Expect mild temperatures that do not vary greatly from one season to the next. Choose any month of the year, and there will probably be a festival because Dubliners simply like celebrating and feel any time of the year is the best time to visit Dublin.
