Go in summer, June to August, for the mildest weather, open highland roads and the midnight sun. For the northern lights, come September to March, when the nights are long and dark but the weather is harsh.

The year at a glance
Iceland is a land of two very different seasons. The ratings key off Reykjavik, where summer brings mild, long days, accessible roads and near round-the-clock daylight, which is why June to August is the peak. The weather is never hot and can change in an instant in any month.
Winter is the trade-off you make for the aurora. From September to March the long, dark nights give the best chance of northern lights, but storms, ice and short daylight close much of the interior. Spring and autumn are quieter shoulders with a mix of both.

Where you go changes when you go
Reykjavik and the south
The mildest, most accessible part of the island, and the base for the Golden Circle and south-coast waterfalls.
The Highlands
The interior roads only open in summer, roughly late June to early September, for the most dramatic, remote scenery.
Aurora country, in winter
From September to March the dark skies anywhere away from city lights offer the best chance of the northern lights.
Best time to visit Iceland for
The Ring Road and highlands
June to August, when all roads are open, the weather is mildest and the days are endless.
Northern lights
September to March, on clear, dark nights away from town. October, February and March balance aurora odds with manageable conditions.
Midnight sun
June and July, when the sun barely sets and you can hike or drive late into the night.
Fewer crowds
May and September are quieter shoulders with a chance of both decent weather and early or late auroras.
What is on, and when
Midnight sun, June and July
Near round-the-clock daylight opens up long evenings of hiking and driving.
Northern lights, Sep to Mar
Dark, clear nights give the best chance of the aurora dancing overhead.
