What's worth planning around in October
- Most F-roads close by mid-October, the last realistic window for Highland access without a 4x4 tour.
- A strong Northern Lights month with genuinely long, dark evenings.
- Iceland Airwaves, the country's best-known music festival, sometimes lands in very early October depending on the year, though its main dates typically fall in November.
- The first day of winter (fyrsti vetradagur), on the old Icelandic calendar, falls on a Saturday between October 21st and 27th. In Reykjavík, merchants along Skólavörðustígur have historically handed out free meat soup to mark the occasion.
