November trade-offs

  • Only 3.5 hours of sunshine daily — sightseeing is severely restricted; what you see you see in the dark
  • Cold and wet: wind chill, ice, and heavy rain make outdoor time challenging
  • Limited tourism services: some guesthouses, tour operators, and restaurants on reduced winter hours

September trade-offs

  • Temperatures drop quickly (10°C high); warm layers essential and weather windows shorter
  • Highland F-roads closing progressively through September — some interior routes blocked by late month
  • Aurora is back but not yet at winter frequency — nights still shorter than January–March
