June trade-offs
- ↓Accommodation prices peak — budget options in Reykjavik at their most expensive of the year
- ↓Crowds building fast: Golden Circle and Blue Lagoon noticeably busy, key spots requiring advance booking
- ↓No aurora is possible — nights never get dark enough for sightings until late August at the absolute earliest
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
