How To See The Northern Lights In Ireland 2023/2024

Yes, you can see the Northern Lights in Ireland, but a number of factors need to fall into place for them to be visible.

The Northern Lights/Aurora Borealis have been fascinating people in Ireland and beyond for centuries.

However, in recent years, likely thanks to social media coverage, sightings of this natural wonder seem to be more common.

You’re most likely to see Aurora Borealis in Ireland during certain months and in very specific parts of the country, as you’ll discover below.

Some quick need-to-knows about seeing the Northern Lights in Ireland

Seeing the Northern Lights in Ireland is a bucket list item for many. Let’s get you up-to-speed on the need-to-knows first:

1. How they form

The Northern Lights are formed when charged particles collide with the earth’s magnetic field causing the release of energy in the form of light. The light varies in colour depending on the type of particles. For example, oxygen molecules deliver a greeny/yellow colour.

2. The months they’re most likely to be visible

You’re most likely to see Aurora Borealis in Ireland between the months of October and April when geomagnetic activity (measured with a Kp number between 0 and 9) hits 4 or above. They’re most likely to be visible between midnight and 02:00.

3. Where to see them

The most common places to see the Northern Lights in Ireland are from the west and north coast in areas with little to no light pollution. Places like the Inishowen Peninsula (Donegal), the Mullet Peninsula (Mayo) and the Causeway Coast (Antrim).

4. Monitoring their visibility

There are several ways to know if you can see the Northern Lights in Ireland tonight. The first is by proactively monitoring the swpc.noaa.gov website. You can also use a free or paid alert service (info below).

How to know when Aurora Borealis is visible in Ireland

More often than not, people trying to see the Northern Lights in Northern Ireland and the Republic are left disappointed.

However, on those special occasions when the conditions are just right, an experience like no other takes place.

Here’s a quick checklist that explains very clearly how to know when the Northern Lights in Ireland are visible.

1. The right solar conditions are key

In order to be able to see Aurora Borealis in Ireland, geomagnetic activity needs to reach a certain level.

This level is measured on a scale of 0 to 9 with a Kp number. In a nutshell, the higher the Kp number is, the larger the Aurora is.

A very handy resource is the swpc.noaa.gov website. The have a scale that’ll show you how likely it is that Aurora will be visible.

2. Clear skies are essential

3. Get to an area with low light pollution after midnight

The final step, once conditions are right, to seeing the Aurora Borealis in Ireland is to get to an area facing northward with very little light pollution.

I’ve stuck a map of the locations below (scroll down a bit) but arguably the best place to see the Northern Lights in Ireland is the west and north coast.

4. Use an alert service

There are a number of different ways that you can get notified when the Northern Lights are visible in Ireland.

If you use Twitter, there’s the Aurora Alerts Ireland. This is an active account dedicated to providing updates. Another good Twitter account is Alan O’Reilly’s Carlow Weather.

We get emails constantly asking what is the best place to see the Northern Lights in Ireland. The map above will give you an insight into the places that Aurora Borealis is most frequently visible from.

Counties Donegal, Antrim, Sligo and Mayo are the key areas, however, the lights have been visible from many other places in Ireland, as you’ll see below.

County Donegal

You can see the Northern Lights in Donegal reasonably frequently. Some of the most common places they can be seen are from the Fanad Peninsula, the Inishowen Peninsula and the Rosguil Peninsula.

You’ll often see photos of the Northern Lights at Malin Head (Inishowen) – the most northerly point in Ireland.

County Mayo

If you’re looking to see the Northern Lights in Mayo, your best bet is to head to either Achill Island (Minaun Heights, in Particular) or to the North Mayo Coast.

Places like the Mullet Peninsula, Downpatrick Head or any location along the north coast with little/no light pollution are all great vantage points.

County Sligo

There have been regular sightings of the Northern Lights in Sligo in recent years, most frequently from the Mullaghmore Peninsula.

Mullaghmore is a little peninsula a short drive from Sligo Town with some great viewpoints facing northwards.

Northern Ireland

You tend to see the Northern Lights in Northern Ireland from the Antrim Coast (Dunluce Castle, the Giant’s Causeway and Whiterocks Beach, in particular).

Aurora Borealis has also been seen from parts of County Tyrone as recent as March of 2023.

County Dublin

It’s very, very rare that you’ll see any trace of the Northern Lights in Dublin, however, some news outlets online would lead you to believe otherwise.

The most recent sighting of Aurora Borealis in Dublin was in early 2023, with travellers aboard flights from Dublin to the UK posting photos of the sky above the capital alight.

County Kerry

Although rare, it has been possible to see the Northern Lights in Kerry in recent years. Ideally, you’d want to be in the Dark Sky Reserve and facing north.

Another possible location would be from Valentia Island where light pollution is very low.

County Galway

Although it’s reasonably rare to see the Northern Lights in Galway, it can be visible there at certain times, usually from parts of Connemara.

In recent years, it was visible in Spiddal, Moycullen and the Mutton Island Causeway.

It was also visible from Cloughduv, not far from Cork City.
