Zermatt: a 13-degree swing in one day out

Clear skies over the Valais this week, and the numbers tell the shoulder-season story. Mornings in Zermatt sit near 7 degrees, afternoons climb to 20. That is a 13-degree swing between the first hour and the warmest one. Pack a merino base layer and a windproof shell: you start cold and finish warm without a bulky midlayer riding along all afternoon. The gap only widens from here.
