Worth Going Out

Northern lights in Inverness in April

Scotland, United Kingdom. Figures for April 2027, calculated by us. Times are local.

Go

Yes, with shorter nights. In mid-April the sky is dark enough for the aurora from about 22:04 to 04:28, 6.3 hours a night.

Darkness through the month

1 April: 7.8 hours of darkness.
15 April: 6.3 hours.
End of April: 4.5 hours. The nights are getting shorter through the month.

“Dark” here means the Sun is more than 12° below the horizon. Faint aurora needs a darker sky; a strong display can show earlier in the evening.

The Moon in April 2027

New Moon: 6 April 2027. The week around it has the darkest skies.
Full Moon: 20 April 2027. A bright Moon makes the aurora look fainter, though it is still there.

What to expect

The aurora appears only on active nights, and only where it is clear. Plan several nights and check the forecast each day: how to read it.
Scotland only sees the aurora during stronger geomagnetic storms, low in the northern sky. Treat it as a bonus, not a reason to travel; watch the NOAA forecast and look north from somewhere dark.
