Start on Grafton Street, Then Follow the Lights North
By mid-November the Christmas season has already begun in Dublin, and the switch-on of the Grafton Street Christmas lights — usually falling between 15 and 17 November — is the moment the city commits. It is a free public event with live music and fireworks, and it marks the informal start of Christmas here. Henry Street's curtain lights are switched on around the same time, so you can walk both premier shopping streets in one evening: Grafton Street for Brown Thomas, Marks & Spencer, Tommy Hilfiger and Dunnes Stores, with buskers along the way and a live Christmas tree at the College Green end; Henry Street for the more budget-friendly north-side equivalent, including Penneys, Dunnes Stores and Easons. St Patrick's Cathedral's Christmas tree goes up in mid-November too, and the season runs right through to early January.
Eat and Drink Your Way Through the Markets
The heart of the season is the market circuit, and the biggest is at St Stephen's Green: more than 50 wooden chalets, German-style mulled wine and gluhwein, hot chocolate, sausages, sauerkraut, Belgian waffles, crafts and decorations. It typically opens between 18 and 22 November and runs to 22 December, daily from 11am to 9pm, Sundays 11am to 7pm, with free entry. Smaller and calmer alternatives are worth knowing: the Dublin Castle Christmas Market in Castle Yard, focused on Irish artisan crafts, food and drink; the Smithfield Continental Market on Smithfield Square, which is less crowded and family-friendly; and the Howth Christmas Market, where the regular Saturday–Sunday market expands for Christmas and pairs naturally with the Howth Cliff Walk. If you want a bird's-eye view of the lit-up city, the 30-metre illuminated Big Wheel at Custom House Quay runs from mid-November to early January, at €15 for adults and €10 for children.
Concerts, Carols and the Christmas Stage
Dublin's Christmas is as much a listening season as a shopping one. Carol services are held at St Patrick's Cathedral, Christ Church Cathedral and Whitefriar Street Church, with major services on 23 and 24 December. Bewley's Café Theatre on Grafton Street runs Christmas Cabaret shows daily through December in the afternoon. The Gaiety Theatre stages its annual Christmas pantomime, the Olympia puts on comedy and variety Christmas shows, and the National Concert Hall hosts festive concerts by the Dublin Philharmonic and the RTÉ Concert Orchestra. If you want to end the year at a racecourse rather than a concert hall, the Leopardstown Christmas Races run 26–29 December.
Christmas Eve, Christmas Day and the Forty Foot Swim
On 24 December the city winds down on a schedule worth planning around: it is the last shopping day, most attractions stay open until 4–5pm, major shops close at 6pm, most restaurants shut by 4–5pm, pubs typically close at 11pm, and public transport is reduced. Midnight Mass is the anchor of the night, with St Patrick's Cathedral holding a 10pm carol service followed by 11pm Mass, alongside Christ Church Cathedral and many parish churches.
Christmas Day itself is quiet by design — museums, Dublin Castle, Trinity College and most restaurants are closed, most pubs are shut, and only a small number of hotel bars open for residents. Two things reliably happen. Christmas Day Mass at St Patrick's Cathedral is at 11am. And at 11am at the Forty Foot in Sandycove, swimmers gather to enter roughly 8°C water for charity, watched by hundreds of spectators; some Christmas Day public transport services run to the Forty Foot, and taxis charge premium rates. Many luxury hotels run all-day Christmas dining, but these book out 8 to 12 weeks ahead — Restaurant Patrick Guilbaud at The Merrion (€245–285 per head), The Shelbourne Saddle Room (€180–220), The Westin Mint Bar Christmas brunch (€125), and the Iveagh Garden Hotel Christmas lunch (€65–85) are the benchmarks. A workable Christmas Day shape: 10am Mass, an 11am walk down Grafton Street, a midday train to Sandycove for the swim or to spectate, a pre-booked hotel dinner at 1.30pm, St Stephen's Green at 4pm — it stays open all day — and a hotel bar at 7pm.
St Stephen's Day, New Year's Eve and Where to Sleep
St Stephen's Day, 26 December, is when the city exhales: the Leopardstown race meeting is the major fixture, the Guinness Storehouse, EPIC Museum and National Gallery reopen, hotel restaurants come back, and pubs reopen in the afternoon. The old Wren Boy tradition of costumed children visiting houses survives mostly in rural areas and is gradually disappearing. Between 27 and 31 December most venues return to normal hours and the Christmas market continues, before the New Year's Eve Festival at Custom House Quay closes the season with midnight fireworks.
For a base, the Shelbourne on St Stephen's Green, The Westin at College Green, The Westbury on Balfe Street, The Merrion on Upper Merrion Street and the Iveagh Garden Hotel all run festive programmes, with the Shelbourne, Merrion, Westbury and Iveagh Garden offering 7-night Christmas-to-New Year packages; The Dean on Harcourt Street is the mid-range option with a festive rooftop bar. December afternoon tea is its own ritual — the Shelbourne Lord Mayor's Lounge (€75–85), The Westbury (€65–75), The Merrion Garden Room (€65) and the Iveagh Garden Hotel (€45–55), all booking 6 to 8 weeks out. Expect daytime temperatures of 4–9°C and overnight 1–5°C, a 60–70% chance of rain on any given day, sunrise around 8.30am and sunset around 4.30pm, with snow rare in the city but often visible in the Wicklow Mountains — pack thermal layers, a waterproof jacket, hat, gloves and sturdy boots. Book Christmas-period restaurants 6 to 12 weeks ahead, and note that flights from Dublin Airport are often delayed by weather over the holidays.
Christmas in Dublin rewards a plan made early: the markets and lights run from mid-November to 22 December, the city closes almost entirely on 25 December, and the tables, hotel rooms and concert seats that make the day memorable are gone by the time December arrives. Pick your dates, book the dinner and the room first, and let the lights, the carols and the cold water at Sandycove fill in the rest.
