Worth Going Out

Northern lights in Fairbanks in March

Alaska, United States. Figures for March 2027, calculated by us. Times are local.

Go

Yes: long, dark nights. In mid-March the sky is dark enough for the aurora from about 21:39 to 06:18, 8.5 hours a night.

Darkness through the month

1 March: 10 hours of darkness.
15 March: 8.5 hours.
End of March: 6.3 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 March 2027

New Moon: 8 March 2027. The week around it has the darkest skies.
Full Moon: 22 March 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.
NOAA’s Space Weather Prediction Center names the weeks around the equinoxes, in March and September, as the best season for aurora watching.
Being inland, winter nights are very cold. Dress for well below freezing.
