March is a decent shoulder option for Dublin: fewer crowds, some trade-offs. Expect daytime highs around 10°C, nights near 4°C and roughly 12 rainy days across the month. Mild afternoons near 10C and lengthening days, with the city's biggest event by far around St Patrick's Day on 17 March. The multi-day St Patrick's Festival packs the centre with a parade, street events and full pubs, so book months out and expect peak prices that week; Six Nations rugby can also run into early March.

March is quieter, which makes it the right month to afford the splurge picks.
Special occasions€€€Landmark grand hotel · Creative Quarter and Grafton Street
Dublin's grande dame since 1824, looking straight onto St Stephen's Green with the shops of Grafton Street a minute away. The Irish constitution was drafted upstairs in room 112 in 1922, and afternoon tea in the Lord Mayor's Lounge is still an institution.

First visit€€Design boutique · Temple Bar
A slick boutique on Fleet Street in the middle of Temple Bar, so the trad-music pubs and the Ha'penny Bridge are a two-minute walk from the door. Ask for a room off the street side, as the cobbles stay loud with stag and hen crowds until late at weekends.
from ~155 EUR/night

Couples€€Victorian townhouse · Portobello
A red-brick Victorian on Adelaide Road between St Stephen's Green and the Grand Canal, run as an adults-only townhouse with a candlelit gin and tea parlour. It is a ten-minute stroll to the Green yet sits on a quiet leafy street away from the crowds.

Budget€Modern hostel · Docklands and Silicon Docks
A big, well-run design hostel beside Connolly Station and the Busaras coach station, with private rooms as well as dorms and a busy self-catering kitchen. The airport coaches stop right outside, which makes it the easiest cheap bed for a short break.

With 12 rainy days and highs of 10°C, build your March days around indoor anchors and treat sunny windows as a bonus.
Guinness Storehouse
TipBuy a timed ticket online, which is cheaper than the gate price and skips the queue at Ireland's most visited attraction; the self-guided route climbs seven floors to the Gravity Bar and your included pint. Go for the first slot at opening or late afternoon to dodge the mid-day crush, and allow about two hours all in with the rooftop city view.
Kilmainham Gaol
TipThis former prison, where leaders of the 1916 Rising were held and executed, is run by the OPW and seen only on a guided tour that books out days or even weeks ahead in season. Reserve online the moment your dates are set, since same-day tickets are rare; it sits out west near the Liberties, about 25 minutes on bus 13 or 40 from the centre.
National Museum of Ireland, Archaeology
TipEntry is free, and the standout rooms are the Iron Age bog bodies and the Treasury, with the Ardagh Chalice, the Tara Brooch and a hoard of early Christian gold. It closes on Mondays, so plan around that, and an hour and a half covers the highlights on Kildare Street a couple of minutes from the green.
National Gallery of Ireland
TipFree to enter, the gallery holds a Caravaggio rediscovered in a Jesuit house nearby and the finest room of Jack B. Yeats paintings anywhere. It shelters you well on a wet afternoon on Merrion Square, closes late on Thursdays, and the free floor plan points you straight to the highlights if time is short.
