Best Time to Visit Iceland: Midnight Sun, Northern Lights and Roads

This is the real choice, because you cannot have both. From about mid-May to late July the sky never gets dark enough to see aurora anywhere in Iceland. Around the June solstice the sun dips below the horizon in Reykjavík for only three hours and the sky stays bright; on Grímsey, which straddles the Arctic Circle, it does not set at all. Summer light means you can hike at 10pm, photograph Seljalandsfoss in golden light near midnight and visit the busiest sights after the tour buses leave. Bring an eye mask: many guesthouses have thin curtains.

Northern lights season runs from late August or September to mid-April, whenever the sky is dark and clear. Activity does not peak in midwinter; the equinox months of September, October, February and March often bring strong displays, and they have the bonus of longer days and easier roads. The Icelandic Met Office publishes a cloud-cover and aurora forecast at vedur.is, and cloud is the deciding factor, not latitude: a clear night in Reykjavík beats a cloudy one in the north. Plan at least four or five nights to give yourself a fair chance, and stay outside the towns, because the city lights wash out all but strong displays. Dark-sky spots within an hour of Reykjavík include Þingvellir and the Reykjanes lighthouses, and hotels in the countryside offer aurora wake-up calls.

Golden Circle, south coast and Reykjavík trips work in every month, which is why winter visitors usually stay in the southwest. A full Ring Road loop between November and March is possible but needs flexible days, a 4x4 and comfort driving on snow and ice in the dark; most winter visitors do better with a south coast drive to Jökulsárlón and back, or a flight to Akureyri for the north.

Route 1, the 1,322 km Ring Road, is paved and ploughed all year, but between November and March it closes for a few hours or a day when storms come through, most often on the high stretches in the east and north. Check umferdin.is for road status and safetravel.is for weather alerts every morning, and treat an orange or red wind warning as a reason to stay put. Rental cars in winter come with studded tyres; a 4x4 is not essential on Route 1 but helps on side roads and icy car parks.

The highland F-roads are a summer-only network. Safetravel describes them as usually closed from mid-September until June or July; in practice most open between late June and mid-July and stay passable until early September, depending on snowmelt and the first autumn snow. They lead to Landmannalaugar, Kerlingarfjöll, Askja and the Sprengisandur and Kjölur crossings. You need a 4x4 by law, and some routes need a high-clearance vehicle for river fords. No rental insurance covers damage from river crossings, so if you are unsure, wait for another car or turn back.

Atlantic puffins nest in Iceland from mid-April to mid-August, and the colonies are fullest in June and July. The easiest viewing spots are the Dyrhólaey headland near Vík (closed to visitors during part of the May to June nesting season), the cliffs at Látrabjarg in the Westfjords, the boardwalk colony at Borgarfjörður eystri in the east, and Heimaey in the Westman Islands, which has the largest colony in the world. From Reykjavík’s Old Harbour, short boat trips circle the puffin islands of Akurey and Lundey from May to August. Go in the evening, when birds return from fishing. By the end of August they have gone to sea.

Whale watching runs year-round from Reykjavík, with minke whales, humpbacks and white-beaked dolphins in Faxaflói Bay, but the best trips leave from Húsavík in the north from April or May to October. June to August has the highest odds, with humpbacks on most trips and occasional blue whales in early summer; the Húsavík Whale Museum beside the harbour is worth an hour before you board. Akureyri and Dalvík run trips in Eyjafjörður with similar species. Expect about ISK 13,000-16,000 (roughly US$105-130) for a three-hour boat trip; winter sailings are rougher and more often cancelled.

Arctic terns arrive in May and dive-bomb walkers near their nests until August, and reindeer graze around Egilsstaðir and the Eastfjords all year, coming down to the coast in winter.

The blue ice caves inside Breiðamerkurjökull, an outlet of Vatnajökull near Jökulsárlón, form fresh each year from meltwater channels and can only be entered safely when they are frozen solid, roughly November to March. After a fatal collapse during a summer tour in August 2024, operators and the national park keep cave visits to the cold months. Every visit is with a licensed guide, who supplies a helmet and crampons and drives you from a meeting point at Jökulsárlón or Skaftafell in a modified 4x4. Expect ISK 25,000-35,000 (US$200-280) for a 3 to 4 hour tour, and book a few days ahead in February, the busiest month. Tours are cancelled in heavy rain or warm spells, so schedule the cave early in your south coast stay.

Year-round alternatives exist. Guides take groups into an ice cave in Mýrdalsjökull, the Katla glacier, from Vík in every month, and glacier walks on Sólheimajökull and in Skaftafell run all year. The man-made tunnel inside Langjökull, reached from Húsafell, is open in summer as well as winter. None of them match the colour of a natural winter cave, but they are a safe choice in summer.

July and early August are the peak of demand. Rental cars, campervans and rooms in small south coast towns like Vík and around Skaftafell sell out months ahead, and prices for a double room can be double the winter rate. The Golden Circle stops at Geysir and Gullfoss are busiest from 10am to 4pm in every month, so go early or late. Christmas and New Year form a second short peak, as Reykjavík’s New Year’s Eve bonfires and fireworks draw a crowd.

The shoulder seasons are the best value. In May the days are long, the weather is often the driest of the year, and prices are 20 to 30% below July, although some highland and Westfjords services have not opened yet and snow can linger in the north. The first half of September has summer-length days, red autumn colours, the return of aurora and all the Ring Road services still running; after mid-September some rural guesthouses and cafés close until May. October, November and late January to April are the cheapest months outside Christmas. Our Iceland costs guide lists prices by season, and the getting around guide covers car hire, buses and domestic flights.

Dates below are fixed or follow published rules; event dates are set by organisers, so check before you go.

Christmas Eve is the main celebration, and from about 4pm on 24 December most shops, restaurants and even some petrol stations close until 26 December, so stock up beforehand. The Þjóðhátíð weekend fills every ferry and bed on Heimaey and is a big reason the Westman Islands are booked out in early August.
