Open, 29º, a few new snow flakes. Loose granular on a hard base. Good skiing fast, but skiable. The new snow flakes will help slow the skiing down. Low trails open, 10km.
Carry a knapsack. If you overdress you can carry your extra clothes.
When Nordic skiing we all warm up quite a bit. So that makes it a great sport for cold weather (No chairlift). Sweating does happen. A dry shirt to wear for your second lap and/or to wear home is really nice.
