We are traveling to Switzerland on September 20th. We will be staying in Wengen for 5 nights and Zermatt for 3 nights. We are planning to do some long day hikes and a trip to Jungfraujoch. Weather seems to be quite variable at this time of year, but what are the typical daily highs and lows in late September? Should we plan to bring down jackets, or will a few layers suffice? Are thunderstorms typically an issue for long hikes this time of year?
Thanks for any info/tips you can provide!
