When can you see the northern lights in Ireland?
When can you see the northern lights in Ireland? You are most likely to see Aurora Borealis in Ireland between October and April when geomagnetic activity hits 4 or above. Keep in mind that the skies need to be clear for the lights to be visible.
Do the northern lights happen every night?
Fortunately, they occur frequently. The northern lights are happening 24 hours a day, seven days a week, 365 days a year, said photographer Chad Blakely, owner of the northern lights tour company Lights Over Lapland. But that doesn't mean they're easy to spot; you need to be at the right place at the right time.
