The verdict
Choose Belfast if you want a city trip: restaurants and a range of kitchens, bars and clubs, museums, sights within walking distance of the centre, and protected countryside around it, with the sea 1km away.
Choose Killarney if the town matters less to you than the quiet. It is a place of 14,400 people with little dining, nightlife or sightseeing, and the coast 18km off.

Where they differ
Belfast is the one with an evening: many more places to drink, and nightclubs, which Killarney lacks, most of them near the centre. It also has much more park space and protected countryside, 19% of the surrounding land against 1%, and far more for children, including 2 theme parks within reach.
Killarney is a town of 14,400 with few places to eat or drink and fewer attractions. Its coast is 18km from the centre, with 6 beaches, though its sea is the milder of the two, reaching 16°C.
Where they are alike
Both are mild and narrow in range through the year, Belfast 7-19°C, Killarney 10-18°C, and neither gets a properly dry month: nowhere in either calendar does rainfall fall to 40mm or less. Winters are cool rather than cold, summers warm rather than hot.
They share a cold sea too: neither reaches 21°C in any month, so swimming is brief and bracing rather than a reason to go. Neither is a heritage-led trip either.
Which traveller are you?
Eating and drinking your way through a weekend: Belfast, with many times the number of restaurants near the centre and a wider range of kitchens, plus bars and clubs that Killarney has little of.
Travelling with children: Belfast again. Attractions and park space sit near the centre, 2 theme parks are within reach, and the sea is 1km away with 10 beaches nearby, though not for long swims at 14°C.
Wanting a small, quiet base rather than a city: Killarney, a town of 14,400 with mild winters. Expect to travel 18km to the coast and to make your own entertainment in the evenings.
What the numbers don't tell you
No cost comparison is possible here. The dataset gives a daily budget for Killarney, €187, and none at all for Belfast, so nothing in these figures tells you which is the cheaper trip. The value ratings rest on a separate measure.
The beach figures flatter both. Belfast has 10 beaches nearby, but the sea never gets past 14°C, so a high beach count says more about coastal walking than swimming. Rainfall is the other blind spot: no month in either place drops to 40mm or less, so a warm month is not a dry one, and Killarney's mildest winter weeks are also its wettest.
When should you go?
The figures behind each month. Each row is shaded against that destination's own year, so the deepest cell is its best month for that measure and the palest its weakest. Shades are not comparable between the two rows.
Temperature and rainfall are thirty-year climate normals, averaged over the years shown. Belfast: 1991-2020 normals, Belfast / Aldergrove Airport (19.4 km from centre). Killarney: 1991-2020 normals, Valentia Observatory (52.7 km from centre).
Belfast's window is May to August, when highs run 15-19°C and rainfall sits at its lowest for the year, around 55-65mm a month. From October the pattern turns, near 89mm, and it stays wet through the winter.
Killarney is at its best in August, its warmest month at 18°C with the sea up to 16°C, and its driest stretch falls in May, near 91mm, still wetter than anything Belfast gets. Winter is the reason to avoid it: the darkest months approach 187mm.

The busiest departure cities for these two, with a place kept for each other part of the world. Busiest means arriving passengers where an official count exists, and where none does, the number of non-stop services flown: official route statistics are published by the European reporting countries and by nobody else, so a table ranked on them alone would offer a reader in New York or Tokyo ten European cities. Flying times are estimated from the distance between airports, and every row is a city flown non-stop to both. Where the typical offer connects anyway, the stops are shown. Under each figure is the airport the flight lands at and how far that is from the centre, because the nearest airport is not always the one a route is flown to. Where both columns name the same airport it is one flight, and the difference between the two is the distance printed beside it. Typical return fares for 2026-08 to 2026-10, cached market data up to 7 days old. The figure is the middle half of the offers found, so a single price means they agreed and a range means they did not; for a typical route that middle half spans about a quarter of the median, and for the least settled routes rather more than the median itself.
