Rank the 12 months for your interests
What this solves
The "best time to visit Iceland" answer in most blogs is "summer, June-August, when it's not cold and dark" — which is the worst possible advice for someone wanting to see the aurora. The real answer is: it depends on your interest.
This tool scores each of the 12 months against 8 visitor interests. Aurora visibility requires dark skies + clear weather + solar activity. Midnight sun requires being there around the solstice. Puffins are only present May-August. Skiing only works in winter. Festivals cluster in summer.
How to read the result
Each month shows: month + year, overall score (0-100), breakdown by interest. The list is sorted by overall fit. Note: the score balances your interests with price/crowd factors.
Limitations
The scores reflect typical Iceland weather, not specific year conditions. 2024 had an unusually warm winter (fewer auroras due to cloud cover). 2025 had a dry summer (better hiking). Always check current forecasts.
Aurora visibility depends on solar activity (currently high in 2024-2026 due to solar maximum), KP index, and cloud cover — all unpredictable months in advance.
FAQ
When is the cheapest time?
November or January. Just before Christmas is expensive; just after is cheap. The shoulder season trick: book late September or late April for value + decent weather.
When is the aurora most likely?
September and March — equinox months. There's a real aurora-season equinox effect where geomagnetic activity is statistically higher. Plus these have more dark hours than deep winter.
When can I see puffins?
Late May to early August. Peak in early July.
