Planning a trip to Dublin? This guide provides insights into what to expect during each season, helping you make the most of your visit, no matter what time of year you choose.
High Season: June–August
Best for: Good weather and long daylight hours
June to August is considered the high season in Dublin, attracting visitors with warmer days and a bustling event schedule. Summer is ideal for those wanting to enjoy pleasant weather, with average temperatures ranging from 16 to 20 degrees Celsius (60–68 ºF). Sunshine is common, but Dublin’s weather is unpredictable, so be prepared for clouds and rain.
Summer is also the peak season for tourism, meaning accommodation is harder to find and prices are higher. Booking well in advance is essential to secure your preferred lodging and avoid inflated rates.
Dublin’s summer is packed with festivals and events. Music lovers can enjoy large gatherings like Forbidden Fruit and Longitude. June hosts the vibrant Pride celebrations, spanning a week of festivities. Bloomsday, a uniquely Dublin event, takes place on June 16th, celebrating James Joyce’s Ulysses with Edwardian-themed revelry. Another distinctive event is the Liffey Swim, where 500 participants swim 2.2km along the River Liffey. Art enthusiasts can visit the National Gallery to see Jack B Yeats’ famous painting depicting this event. Foodies should head to Herbert Park in mid-August for The Big Grill, Europe’s largest barbecue and food festival, showcasing Irish and international chefs cooking over live fire.
The Dublin Horse Show at the Royal Dublin Society (RDS) is a major social event in summer. This long-standing institution combines a garden party atmosphere with an agricultural show. The highlight is the Aga Khan Trophy, a thrilling international show jumping competition.
Summer is perfect for exploring Dublin on foot. Wander through St Stephen’s Green, browse Grafton Street’s shops, and enjoy street performers. Relax in a traditional pub with a pint of Guinness. Take a short DART train ride to Dublin’s beautiful beaches, from Killiney to Balscadden Bay. Stroll along Sandymount Strand, enjoy cliff views on the Howth cliff walk, or swim at Forty Foot Pool, Portmarnock, or Seapoint.
Shoulder Season: March–May
Best time for: Festivities and fewer crowds than summer
Dublin transitions from winter around mid-March with the St Patrick’s Festival, a multi-day celebration around March 17th. The St. Patrick’s Day parade attracts half a million people, creating a lively but crowded atmosphere. Outside of St. Patrick’s Day and Easter, accommodation rates are more attractive, and the city is less crowded than in summer.
April’s main event is the Grand National at Fairyhouse in County Meath, held on Easter Monday. The Five Lamps Festival in April celebrates the creativity of Dublin’s north inner city over nine days. May sees Dublin preparing for summer with the International Dublin Gay Theatre Festival and the International Literature Festival Dublin.
Spring is an ideal time to escape the city’s St. Patrick’s Day crowds and explore Dublin’s parks and gardens. Visit the National Botanic Garden with its Victorian greenhouses and exotic plants, or St Anne’s Park with its Roman-style architecture. Enjoy local produce at the Red Stables Food Market at St Anne’s on Saturdays or browse artisan crafts and food at Herbert Park on Sundays.
Shoulder Season: September–October
Best for: Good weather and thinner crowds
The high season ends in September, with schools reopening and tourist crowds decreasing, leading to lower accommodation rates. Booking in advance can secure even better deals.
September and October often bring pleasant weather, with average highs around 16ºC (60ºF), and occasional late summer warmth. This makes it a great time to combine indoor and outdoor activities. Consider a day trip to Glendalough, now less crowded, followed by a performance at the Fringe Festival in September or the Dublin Theatre Festival in October.
Autumn evenings are perfect for exploring Dublin’s cultural side. Visit the Abbey Theatre or discover lesser-known museums. Culture Night, on the second to last Friday of September, features free events and workshops celebrating Irish culture throughout the city. October brings the Bram Stoker Festival, offering gothic entertainment in honor of the famous author.
Low Season: November to February
Best for: Cozy pubs and indoor cultural experiences
Dublin winters are damp, cold, and often dreary, making it the perfect time to seek refuge in a cozy pub snug. With around 800 pubs citywide, options abound, such as Kehoe’s or The Long Hall. Live music venues like Whelan’s are great for indoor entertainment.
Dublin, a UNESCO City of Literature, hosts the Dublin Book Festival in November, with events at over 80 venues, including author talks and literary walks. Host locations include the National Library of Ireland and the National Botanic Gardens.
From November to late January, Winter in Dublin features events and a large New Year’s Eve festival across the city center. Dublin shines with holiday lights in December. Stroll from O’Connell Street to Merrion Square Park to enjoy the displays. Visit the Dublin Castle Christmas Market or the Dun Laoghaire Christmas Festival with its ice rink.
Many Dublin pubs serve holiday-themed pints, with pubs like Hole in the Wall and The Ginger Man known for elaborate decorations. Afternoon tea at luxury hotels like The Shelbourne offers a festive treat.
For a traditional Irish Christmas, attend carol services at St. Patrick’s Cathedral or visit the Moving Crib holiday display. The Christmas Eve busk on Grafton Street is a free outdoor charity concert. Brave locals take a Christmas morning swim in the Irish Sea at locations like the Vico Bathing Place or Forty Foot.
January and February are quieter months, ideal for exploring museums or independent cinemas like the Light House Cinema or the Irish Film Institute.
The National Gallery displays JMW Turner watercolors only in January to protect them from light, a tradition maintained since 1900.
February marks the start of the Six Nations rugby championship, creating a lively atmosphere in Dublin, even for away games. The Dublin International Film Festival in February showcases Irish and international films.
Winter in Dublin is ideal for enjoying hearty meals like beef and Guinness stew or Dublin coddle in a warm pub. For a tranquil escape, take a winter walk in Wicklow Mountains National Park or along the Howth cliffs.
