Anytime from now until the end of March is good aurora viewing here in Fairbanks. A new moon, (no moon), is best as the light from the moon can take away from the lights. The area north of town 20 miles up the Steese Highway called Cleary Summit is one of the best viewing areas on the planet. This is where we live and along with two of our neighbors have condo/lodges that cater to aurora viewers. The ski area up here also caters to viewers.
In late October we will more than likely have snow and will have freezing temps.
