RV + dark skies
Northern lights by region
The aurora is the one trip you can't put on a schedule — it's driven by geomagnetic activity and needs a clear, dark, moonless sky. But you can stack the odds: get to a dark-sky park in season and watch the NOAA Space Weather forecast. Here's where to point the rig by region, honestly — Alaska is the closest thing to a sure bet; the lower-48 spots are real but occasional.

Dark, clear, moonless nights are the whole game — and check the NOAA forecast first.

Aurora is not a season the way a bloom is. The light is produced by the sun, arrives on a two-to-three-day lag after a coronal event, and can appear on any clear night of the dark half of the year. What the windows on these pages describe is therefore not when aurora happens but when you can SEE it: how many hours of true darkness the latitude gives you.
That is why three of these sites state a season without naming a month. At this latitude the limit is darkness and cloud, and both move with the year rather than with the calendar. Watch the NOAA space-weather forecast in the days before you drive, not the month on a chart — and give yourself several nights, because one clouded night is the whole trip.
