Open, 18º and partly sunny. Forecast high 37º and partly sunny, 25 km good skiing. Variable conditions depending on the temperature, time of day and sun.
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.
