Best time to visit Dublin from the UK

May through September is the best time for British visitors. Temperatures are mild at 14C to 20C and the days are long. June is popular for outdoor pub culture and the summer solstice. St Patrick's Day (17 March) is the city's biggest festival and draws huge crowds from the UK. October through March is quieter with cooler temperatures of 4C to 10C and the lowest prices. Dublin has world-class pubs, galleries, and restaurants year-round regardless of weather.

Airport and Transit Connectivity

Dublin Airport (DUB) has 4G and 5G coverage across Terminal 1 and Terminal 2. Your HelloRoam eSIM connects to the network before you reach the arrivals gate. The Aircoach and Dublin Express bus services connect the airport to the city centre in 30 to 45 minutes with outdoor 4G throughout.

The Dublin Bus 16 and Airlink 747 routes also run from the airport. The Luas Green Line runs from the suburbs to central Dublin and the DART connects the coastline. Dublin city centre has no metro system, so buses and trams are the main public transport.

The Dublin Bikes app and various car rental apps all need live data. British travellers arriving here should check they have their data active before leaving the arrivals hall.
