October is the best month to visit Northern Ireland and it is not close.
You get autumn colour in the forest parks, the coast at its most dramatic, Europe’s largest Halloween festival, a four-week arts festival across thirty Belfast venues, and prices that have dropped from the July peak. Almost everything is still open. The only thing you give up is daylight, and there is a specific date in October when you give up a lot of it at once.
Crossing the border? Two currencies, two sets of speed limits and a hire car insurance trap that catches people out. Here is everything that actually changes when you cross between Ireland and Northern Ireland.
Northern Ireland weather in October
Belfast averages a high of 13°C and a low of 7°C, with about 95mm of rain spread over roughly 14 days of the month. So it rains on about half the days, but rarely all day. The pattern here is showers and bright spells rather than the steady grey of November.
The coast is windier and a few degrees cooler in the wind. The Mournes and the Sperrins can be genuinely cold and wet at height while Belfast is mild. Pack a waterproof with a hood, because an umbrella on the Causeway Coast in October is a novelty item.
Flying from the US?
Most Americans pay too much to get to Ireland.
I send one email a week with the best fares from US airports into Dublin, Shannon and Belfast, plus what to actually do when you land. $14.99 for the year, refunded if it does not pay for itself.
Daylight in October, and the date that matters
This is the practical thing nobody tells you, and it changes how you plan.
- 1 October: sunrise 07:26, sunset 18:59. Eleven and a half hours of daylight.
- 15 October: sunrise 07:52, sunset 18:25. Ten and a half hours.
- 31 October: sunrise 07:24, sunset 16:49. Nine and a half hours.
The clocks go back on Sunday 25 October. On the Saturday, sunset in Belfast is just before six. On the Sunday, it is just before five. You lose an hour of usable evening light overnight, and it is the single biggest planning variable in the month.
If you are here to photograph the Causeway Coast or drive the Antrim glens, come in the first three weeks and you get long, low, golden afternoons. Come in the last week and you are finishing outdoors by half four. That is fine if you are here for Halloween, because Halloween happens after dark anyway. It is not fine if you have driven from Belfast to the Causeway and left at noon.
Derry Halloween 2026: 28 October to 1 November
Derry does the biggest Halloween festival in Europe, and it is the single best reason to be in Northern Ireland this month. The 2026 dates are Wednesday 28 October to Sunday 1 November.
The core of it:
- Awakening the Walled City Trail, three nights of illuminated installations and performances through the city walls
- The Carnival Parade, a grassroots parade through the city centre
- Fireworks over the Foyle as the finale
- Little Horrors for younger children, plus tours, trails and gigs across the city
Most of the street programme is free. Some indoor and ticketed events sell out well ahead. The city fills completely across the 30th and 31st, and it is a genuine costume city rather than a few people in masks, so turning up in ordinary clothes will make you feel like the odd one out.
I have written the full breakdown, including where to stay when Derry is full and how to do it with children, in the Derry Halloween guide, and there is a wider round-up in Halloween events across Northern Ireland.

The fireworks, and where to stand
The carnival parade and the fireworks are the finale, and both are on 31 October. The parade sets off around 7pm from the quay and works along the Strand Road and the Embankment. The fireworks follow at roughly 8.15pm, weather permitting.
Go by the date rather than the day. The official programme lists the finale as “Friday 31st October”. In 2026, 31 October is a Saturday. The date is right and the day is wrong, and it is not the first time the published information has had that problem.
The fireworks are launched from two barges out on the River Foyle, so there is no single best spot. Anywhere along the water between the Peace Bridge and Fort George will give you the display, and the council actively asks people to spread out rather than all pile onto the same stretch of quay.
Here is the bit that catches people out. The Peace Bridge closes for the display, in past years from about 7.45pm until 8.45pm. If you are staying on the Waterside and planning to walk across for the fireworks, cross early. Otherwise you will watch from the wrong side and then wait an hour to get back over. Worth knowing before you book a bed there. Our full Derry Halloween guide covers where to stay on each side of the river.
Belfast International Arts Festival: 14 October to 8 November
The other big one, and much less known to visitors. The 2026 festival is the 64th, running Wednesday 14 October to Sunday 8 November, with over 200 events across around 30 venues including the Lyric, the MAC, Ulster Hall, Queen’s Film Theatre and City Hall. It opens on 14 October with Orchestra Baobab.
If you are in Belfast for a weekend in late October, check the programme before you book anything else. It is the reason the city feels busy on a wet Tuesday in a way it does not in November.
The history bit: Samhain was not invented for tourists
Derry markets itself as the home of Halloween and gets some eye-rolling for it. The claim is better than people assume, and the reason sits about seventy miles south of the city.
Samhain was one of the four quarter festivals of the Irish year, marking the end of harvest and the start of winter. It was a threshold: the point at which the boundary between the ordinary world and the otherworld was thin enough to cross. That idea, rather than any later import, is where the costumes and the guising come from. You dressed as something from the other side so that anything crossing over would take you for one of its own.
What makes this a Northern Ireland story rather than a general Irish one is where those Samhain assemblies happen in the literature. In the Ulster Cycle, the great gatherings are at Emain Macha, the royal seat of the kings of Ulster, and several of the pivotal episodes turn on a Samhain feast there. Emain Macha is Navan Fort, two miles west of Armagh city, and you can stand on it.
What survives above ground is an earthwork on a hilltop, so go for what happened there rather than what is standing. The Navan Centre next door does the interpretation with costumed guides. Going in the week before Halloween, with the light dying at half four and the field empty, is a considerably better experience than any haunted house.

Where to go for autumn colour
Peak colour in Northern Ireland is usually the middle two weeks of October, though it moves a week either way depending on the summer. The best of it:
Tollymore Forest Park, County Down. The obvious one and still the best. Ancient oak, the Shimna river, stone bridges and follies, with the Mournes above it. Busy at weekends, empty on a weekday morning.
Kilbroney Park, Rostrevor. Oak woodland running up the side of the hill above Carlingford Lough, with the Cloughmore Stone at the top. The view down the lough in October light is the best in the county.
Castlewellan Forest Park. The national arboretum is here, which means a far wider range of trees than a native woodland and a much longer colour season as a result.
Glenariff Forest Park, Antrim. The waterfall walk, and the glen itself. Wet underfoot in October, which is rather the point.
Gosford Forest Park, Armagh. Beech avenues, and quiet. Pair it with Navan Fort and the city.

The coast in October
October is one of the best months for the Causeway Coastal Route, and the Giant’s Causeway is far quieter once the summer coaches stop.
October is the month the Causeway Coast stops being a queue and starts being a coastline. The summer coach traffic drops off sharply after the first week, the Giant’s Causeway visitor centre stays open all year, and the light in the afternoon is the best it gets.
Two warnings. Carrick-a-Rede rope bridge closes in high wind with no notice, and October is the month the wind arrives, so have a second plan. And the coast road between Ballintoy and Ballycastle in a squall is genuinely exposed, so if you are not used to driving in it, do that stretch in the morning.

What closes at the end of October
This is the thing that catches people who book late in the month.
Several of the big National Trust houses shut their interiors for the winter around the end of October or early November, while the gardens, grounds and tea rooms stay open. Smaller independent attractions and some coastal cafés go to weekend-only or close entirely. Seasonal boat trips, including Rathlin sailings, drop to a reduced winter timetable.
The large indoor attractions do not close: Titanic Belfast, the Ulster Museum, Crumlin Road Gaol, the Ulster American Folk Park and the Game of Thrones Studio Tour all run through the winter.
If a specific house is the reason for your trip, check its own page for the closing date before you book flights. Trust opening dates shift by a week or two year to year.
Costs and practicalities
Money. Northern Ireland is pound sterling. If you are crossing from Donegal or coming up from Dublin you are changing currency, and there is no border checkpoint to remind you.
Accommodation. October is mid-season and reasonable, with two exceptions. Derry across the Halloween weekend is the most expensive night of the year in that city and books out months ahead. Belfast on Arts Festival weekends firms up too.
Driving. A car is the honest answer for the Causeway Coast, the Mournes and the Sperrins. Public transport covers Belfast to Derry and Belfast to the main towns well, and covers the coast badly.
Compare car hire for Northern Ireland
School holidays. Northern Ireland schools take a short Halloween break at the end of the month, so family attractions are busier that week and quieter either side.
Sundays. Big shops in Northern Ireland can only open between 1pm and 6pm on a Sunday. That is the law rather than the shop being contrary. It applies to anything over 280 square metres, so supermarkets, shopping centres and retail parks. Small shops, off licences, petrol stations and pharmacies open as normal. Plan your Sunday morning around breakfast and a walk, and leave the shopping until after one.
Where to stay in October
If Halloween is the trip, stay in Derry and book early. If it is autumn colour and coast, base yourself in Belfast for the city and one night on the north coast so you are not driving back in the dark.
Where to stay in Derry
- Bishop’s Gate Hotel. Inside the walls, in the old Northern Counties Club. Named Hotel of the Year 2026 at the Ulster Tatler Awards.
- Shipquay Boutique Hotel. Also inside the walls, small, and everything is on the doorstep.
- Maldron Hotel Derry. Central, reliable and usually the cheapest of the three.

Where to stay in Belfast
One thing before you pick. If you are planning to be out in the evening, stay close to the city centre. Taxis and Ubers in Belfast are harder to come by than you would expect, and in December they are worse. Nearly every hotel will tell you it is within walking distance, but that can mean a mile or two, so check what you are actually agreeing to. Stay in the centre proper and everything is a ten or fifteen minute walk.
If you are not going out at night it matters far less, and somewhere a bit further out is grand.
- DoubleTree by Hilton Belfast City Ten Square. Directly behind City Hall, so you are about a minute from the Christmas market and the middle of everything. It was Ten Square before the Hilton rebrand, in case you are looking for the old name.
- Bullitt Hotel. Cathedral Quarter, noticeably better value, small rooms done properly. You are already among the bars and restaurants rather than walking to them.
- Titanic Hotel Belfast. In the old Harland and Wolff drawing offices, the actual rooms where the ship was designed. I stayed here and really liked it. It is still Belfast but it is not right in the middle, so take it when you are not planning a night out.
Not seeing anything that suits? Here is the full list of places to stay in Belfast.
A four day October itinerary
Day 1, Belfast. Titanic Belfast in the morning, Crumlin Road Gaol in the afternoon, an Arts Festival event in the evening.
Day 2, the coast. Leave early. Dark Hedges, Carrick-a-Rede if the wind allows, Giant’s Causeway in the afternoon light, night in Bushmills or Ballycastle.
Day 3, Derry. Along the coast to Downhill and Mussenden Temple, then into Derry. Walk the walls, then whatever the Halloween programme is doing that night.
Day 4, Armagh. South to Navan Fort and the two cathedrals, then back to Belfast. If you have a fifth day, put Tollymore and the Mournes in it.
Is October the right month for you?
Yes if you want the coast without the coaches, autumn colour, Halloween, or an arts programme.
No if you need long days for a lot of driving, want to swim, or are set on a specific National Trust house interior at the end of the month.
If October will not work, November is quieter and cheaper with two excellent festivals, and December is the Christmas market and winter coast month.
Frequently asked questions

Belfast averages a high of 13°C and a low of 7°C, with about 95mm of rain over roughly 14 days of the month. So it rains on about half the days, but rarely all day. The pattern is showers and bright spells rather than the steady grey of November.
How many hours of daylight are there in Northern Ireland in October?
Eleven and a half hours on 1 October, ten and a half by the 15th, and nine and a half by the 31st. The clocks go back on Sunday 25 October, and you lose an hour of usable evening light overnight. That is the single biggest planning variable in the month.
When is the best time in October to visit the Causeway Coast?
The first three weeks. You get long, low, golden afternoons. Come in the last week and you are finishing outdoors by half four, which is fine for Halloween because that happens after dark anyway, but not if you have driven up from Belfast at noon.
What closes at the end of October in Northern Ireland?
Several of the big National Trust houses shut their interiors for the winter at the end of the month, so check before you build a day around one. Grounds and coastal sites generally stay open.
Is October a good time to visit Northern Ireland?
Yes, if you come prepared for short evenings. It is the month of Derry Halloween, the Belfast International Arts Festival and the best autumn colour, and the summer coaches have gone.
What should you pack for Northern Ireland in October?
A waterproof with a hood. An umbrella on the Causeway Coast in October is a novelty item. The coast is windier and a few degrees cooler in the wind, and the Mournes and Sperrins can be genuinely cold at height while Belfast is mild.
