Aurora forecast / September
Northern lights in Iceland in September
One of the two best months of the year.
September gives you real darkness back while the weather is still comparatively mild and every road, including the highlands, remains open. Like March, it benefits from the equinox effect on geomagnetic activity. For most visitors this is the best balance of aurora odds, accessibility and comfort in the entire year.
How dark does it get in September?
- Reykjavík: 7.5 hours dark enough for aurora
- Akureyri: 7 hours dark enough for aurora
Measured on the 15th of the month — the hours the sun sits far enough below the horizon for aurora to be visible.
Roads and access in September
Everything typically open through the month; F-roads begin closing late September.
What else is happening
Autumn colours in the highlands, far fewer visitors than midsummer, and full road access.
