Northern lights Ireland tonight

Donegal in the northwest sits at 55°N magnetic latitude and needs Kp 5 - the same threshold as northern England. The west coast dark skies and Atlantic-facing headlands give Ireland its best aurora conditions. Dublin, Galway, and Cork need Kp 6 from dark sites outside the cities.

Ireland aurora at a glance

Ireland's aurora advantage is its west coast geography. The Atlantic-facing headlands and peninsulas of Donegal, Connemara, and Kerry have open northern sea horizons with almost no light pollution - conditions that equivalent-latitude cities in England cannot match. Malin Head, the northernmost point of Ireland at 55°N magnetic latitude, is the island's prime aurora position.

The main practical obstacle is cloud cover. Ireland's Atlantic climate brings frequent overcast, particularly along the west coast in autumn and winter. Clear nights are less common than in Scandinavia or continental Europe. When a clear night does coincide with a G2+ storm, the displays can be striking - aurora has been photographed from every county during the stronger events of the current solar cycle.

Common questions

Northern lights in Ireland — thresholds, best locations, and the Atlantic weather factor.

Can you see the northern lights in Ireland?
Yes, during moderate to strong geomagnetic storms. Ireland sits at 52–55°N magnetic latitude. Donegal in the north needs Kp 5 from dark coastal sites; Dublin, Galway, and Cork need Kp 6 or above. During G2–G3 storms (Kp 5–6), aurora is visible across the northern half of the island from dark sites. The G5 storm of May 2024 produced aurora visible across the whole of Ireland including Cork.
Where is the best place to see the northern lights in Ireland?
Donegal gives the best chance in Ireland. At 55°N magnetic latitude, it has the lowest Kp threshold of any Irish county - Kp 5 from the Malin Head peninsula or Glenveagh National Park. The Atlantic-facing cliffs and headlands give north-facing open sea horizons with minimal light pollution. The Inishowen Peninsula around Malin Head is the go-to spot for Irish aurora chasers.
What Kp is needed for aurora in Ireland?
Kp 5 from Donegal and the north coast. Kp 6 from Dublin, Galway, and the Midlands. Kp 6–7 from Cork. At 52–55°N magnetic latitude, Ireland is south of the auroral oval and needs geomagnetic storms to push the oval south to Irish latitudes. G2 storms (Kp 5–6) bring aurora to the north; G3+ storms (Kp 6+) reach the south and west.
When is the best time to see aurora in Ireland?
September to April. Ireland has adequate darkness from September through April. The equinox months of September and March are the most geomagnetically active. Winter gives longer nights but Ireland's Atlantic weather brings frequent cloud cover - cloud is the biggest practical obstacle. The clearest skies are often in the west (Donegal, Connemara, Kerry) rather than the east.
How does Ireland compare to the UK for aurora?
Ireland is very similar to northern England and Wales in aurora threshold terms. Donegal at 55°N magnetic latitude is equivalent to southern Scotland; Dublin and Galway at 53°N are equivalent to Yorkshire or Lancashire. The key advantage Ireland has is darker skies on the west coast - Connemara and Donegal have very low light pollution and an open Atlantic horizon facing north, which gives better conditions than equivalent-latitude English cities.
