Northern lights Dublin tonight
Dublin sits at 53°N magnetic latitude and needs Kp 6 from a dark site outside the city. Howth Head gives an open sea horizon to the north; Sally Gap in the Wicklow Mountains gives the darkest skies within reach. Strong G3+ storms bring aurora to Dublin latitudes several times per solar maximum year. Best season: September to April.

What Kp is needed here?
Dublin sits at a magnetic latitude of approximately 53°N. The Kp index - a global measure of geomagnetic activity on a scale from 0 (quiet) to 9 (extreme storm), updated every 3 hours - needs to reach Kp 6 before the auroral oval expands far enough south to be visible from here.
At Kp 6, visibility is possible from Dublin but skies need to be clear and dark. Cloud cover and light pollution remain the main obstacles even when Kp is high enough.
Best dark sky sites near Dublin
Light pollution is the biggest obstacle after cloud cover. These sites give you the best dark northern horizon within reach.
Howth Head
A peninsula 15 km northeast of Dublin city centre. The cliff paths on the north face give open sea views to the north and northeast with the city glow behind you. Light pollution from Dublin is still visible but the northern horizon is relatively clear. Drive to the Howth summit car park and walk north along the cliff path. Access is straightforward by DART train to Howth village.
Sally Gap, Wicklow Mountains
A high mountain pass at 500 m elevation in County Wicklow, about 45 minutes south of Dublin. The open bogland gives a wide northern sky and the elevation reduces lower-atmosphere haze. Light pollution from Dublin remains visible to the north but the horizon is low and clear. The R759 road through Sally Gap is navigable year-round except in heavy snow. Pull in at the Kippure TV mast car park.
Killiney Hill
A small hill 12 km south of Dublin city with views northward across Dublin Bay. Limited dark sky but a clear northern horizon over the bay. For Kp 6+ events, low aurora on the northern horizon may be visible before it rises above city light. A compromise site when travel to Wicklow or the coast is not possible. Free access via the Vico Road car park.
