We have been to Iceland twice — once in July with a full campervan and the tourist crowds to match, and once in May, almost by accident, because we happened to be driving south from the Faroe Islands ferry. The May trip was quieter, cheaper, and in some ways more beautiful than anything we saw in peak season. If you are considering Iceland in May and wondering whether it is too cold, too unpredictable, or too off-season to be worth the flight — this is our honest answer.

Iceland in May is one of the most underrated travel windows in the Nordic calendar. The roads have reopened after winter, the waterfalls are running hard from snowmelt, the interior is still closed (which is fine — most people never go there anyway), and the midnight sun is already building toward its June peak. You will have places to yourself that are overrun in summer. And the prices are noticeably lower.

Iceland in May is cold (2–10°C), occasionally snowy in the highlands, and unpredictably windy — but it is absolutely worth visiting. Most roads are open, tourist sites are accessible and uncrowded, and the days are already very long. Come prepared for real weather and you will have one of the best Iceland trips possible.

What Iceland in May actually feels like

The first thing to understand about Iceland in May is that it is genuinely spring — not the polished, warm spring of southern Europe, but a raw Nordic one. Snow still caps the mountains. The lowland grass is turning green in patches. The waterfalls — Skógafoss, Seljalandsfoss, the ones you have seen a thousand times in Instagram photos — are louder and more powerful than at almost any other point in the year, because snowmelt is feeding them constantly.

The light situation

By mid-May in Reykjavik you have roughly 20 hours of daylight and the sun does not set until after 11 pm. By the end of May it barely sets at all. This is both a gift and a logistical puzzle — you will need blackout curtains or a sleep mask, and you will lose all sense of time in the best possible way. Northern lights become essentially invisible by late May, so if aurora is your goal, May is borderline; early May is your last real chance before the bright nights take over.

The crowd situation

May sits in what the Icelandic tourist industry calls the “shoulder season.” The Golden Circle, the South Coast, the Snæfellsnes Peninsula — all accessible and all operating at maybe 20–30% of their July capacity. We parked directly in front of Seljalandsfoss. We had the Jökulsárlón glacier lagoon almost to ourselves for an entire morning. If you have been to Iceland in July and felt overwhelmed by the bus queues, May will feel like a different country.

Weather, temperature, and what to pack for Iceland in May

Reykjavik averages 5–10°C in May. The south coast and highlands are colder. Wind is the real issue — a clear 8°C day can feel like −5°C when the Atlantic is pushing in from the west. Rain is frequent but usually comes in fast-moving showers rather than all-day downpours. Snow is possible at any elevation and very likely if you drive into the highlands.

The packing list that actually works

• Merino wool base layer (top and bottom): the single most important item. Stays warm even when wet.
• Mid-layer fleece or lightweight down: you will put this on and take it off a dozen times a day as the weather shifts.
• Waterproof and windproof shell jacket: non-negotiable. Your regular rain jacket from home is probably not windproof enough.
• Waterproof trousers: for waterfall walks and highland stops. Jeans are useless in Icelandic rain.
• Sturdy waterproof hiking boots: trails near waterfalls and on lava fields are wet and uneven. Ankle support matters.
• Warm hat, gloves, buff/neck gaiter: even on a mild day the wind near the coast makes these useful.
• Sunglasses: the low-angle spring sun is blinding on water, snow, and white gravel roads.
• Sleep mask: mandatory by late May. Blackout accommodation is worth paying extra for.

What is open and what is not in Iceland in May

This is the practical question most guides gloss over. Here is the honest breakdown for May.

Open in May

• The entire Ring Road (Route 1): open and fully driveable all year. In May conditions are generally good, with occasional ice on mountain passes.
• Golden Circle (Þingvellir, Geysir, Gullfoss): open and operating. Gullfoss is spectacular in May with full snowmelt volume.
• The South Coast (Seljalandsfoss, Skógafoss, Reynisfjara, Jökulsárlón): all open. This is arguably the best coast to visit in May — powerful waterfalls, manageable crowds.
• Snæfellsnes Peninsula: open. Kirkjufell looks dramatic with residual snow on the peak.
• Most guesthouses, hotels, and camping sites: open, with some smaller properties opening in mid-May.
• The Blue Lagoon: open (book months in advance, even in May).

Closed or restricted in May

• The F-roads (Highlands — Landmannalaugar, Kjölur, Sprengisandur): closed until at least mid-June, sometimes July. Do not attempt these in a standard rental car in May — the bridges are out, the river crossings are dangerous, and your rental insurance will not cover you.
• Some smaller mountain passes: may have temporary closures after a snowfall. Always check road.is before driving.
• Some remote campgrounds: small sites off the main routes may not open until June.

The best places to visit in Iceland in May

Given what is open and the seasonal advantages, these are the areas we would prioritise on a May Iceland trip.

• The South Coast: Seljalandsfoss is accessible from behind in May (something that closes in winter ice). Skógafoss is at full roaring volume. Reynisfjara black sand beach is wild and dramatic in May storms. Jökulsárlón has icebergs calving and almost no buses.
• Reykjavik: the city is pleasant and uncrowded. The restaurant scene does not have the summer premium pricing. The Hallgrímskirkja view from the tower on a clear May evening is one of the best urban views in the Nordics.
• Snæfellsnes Peninsula: this is our favourite part of Iceland in any season, and in May the combination of residual snow on Snæfellsjökull glacier and empty roads is genuinely beautiful.
• The Golden Circle: do it early in the morning in May and you will have Þingvellir essentially to yourself. The geysers erupt on the same schedule regardless of the season.
• East Iceland (Eastfjords): very quiet in May. If you are doing the full Ring Road, the Eastfjords are worth the time — the roads are dramatic, the villages are real rather than tourist-built, and there is almost nobody there.

Iceland in May quick-reference checklist

• ✓ Check road.is every morning before driving — conditions change fast in May
• ✓ Book accommodation at least 4–6 weeks ahead, especially on the South Coast
• ✓ Pre-book the Blue Lagoon months in advance even in shoulder season
• ✓ Rent a 4WD even if you are not going on F-roads — gravel and mud are everywhere in May
• ✓ Pack a full waterproof layer, not just a light rain jacket
• ✓ Download the Veður app (Icelandic Met Office) for local forecasts
• ✓ Bring a sleep mask or book blackout rooms — it is bright by 4 am by end of May
• ✓ Buy petrol whenever you see a station on the Ring Road — gaps are long

Tips and warnings for Iceland in May

• Weather windows move fast. We had three sunny hours and then a full whiteout on the same day near Vík. Always carry your full waterproofs and do not leave them in the car.
• The wind is the real enemy. Car doors can be ripped off in Icelandic gusts. Open doors into the wind slowly and carefully, especially on the South Coast and near exposed headlands.
• Rental cars are significantly cheaper in May than July. A small 4WD that costs €120/day in July might be €60–80 in May. Book early regardless — inventory still runs short.
• Petrol is expensive and stations are sparse. Budget €80–120 per week for a small car doing Ring Road distances, and fill up whenever you have the chance.
• Respect cliff edges at waterfalls. The trails at Seljalandsfoss and Skógafoss are wet and can be icy in early May. Take it seriously — tourists are injured every year.
• Wild camping is technically allowed but limited. Camping outside designated sites is restricted in Iceland, especially in popular areas. Stick to approved campsites, which are open by mid-May at most locations.
• Early May can still feel like winter. Snow is possible all the way into the first week of May, especially north of Reykjavik. Mid-to-late May is warmer and more predictable.

Iceland in May vs June vs September

• May vs June: June is the midnight sun peak and the start of full summer crowds. May is 20–40% cheaper, quieter at every major site, and the waterfalls are arguably more powerful. June is better if aurora is not your goal and you want guaranteed warmth (though “warmth” in Iceland is relative). May wins on value and solitude.
• May vs September: September is the start of aurora season again and also very beautiful, with autumn colours appearing on the moorland. September crowds are smaller than July/August but bigger than May. May has the advantage of building light; September has the advantage of building aurora. They are genuinely close — our preference is May if you are driving the Ring Road, September if you are based in the north and chasing lights.
• The clear winner for what? May wins for: value, uncrowded waterfalls, ring road road trips, and the experience of watching Iceland wake up. June wins for: warmth, midnight sun at its peak, full green landscape. September wins for: aurora, autumn tones, and a second good shoulder-season window.

Mistakes we made in Iceland in May

• We underestimated the wind near the South Coast. Our first attempt to walk behind Seljalandsfoss was cut short by a horizontal spray that soaked everything through our outer layers in about two minutes. We had to go back to the car, change, and return properly equipped an hour later. Pack a face cover.
• We drove too fast on the Ring Road. Iceland rewards stopping. A road that looks unspectacular on Google Maps will suddenly reveal a waterfall, a seal colony, or a lava field the moment you get out of the car. We lost two days’ worth of discoveries because we were trying to hit a daily distance target.
• We did not book the Blue Lagoon far enough in advance. Even in May it was sold out for two of our three days when we checked. Book this the same week you book your flights.
• We assumed the F-roads might be passable. They were not. We wasted half a morning driving to a closed gate on the Kjölur route, reading the sign, and driving back. Check road.is in advance and accept that the highlands are a June-onwards thing.
• We skipped the Eastfjords to “save time.” We still regret it. Everyone who has done them says the same thing: slow down and go east.

Frequently asked questions about Iceland in May

A final word from Rovaniemi

We live in Rovaniemi, on the Arctic Circle in Finnish Lapland. Our bar for “cold” is a little different from most people’s — so when we say Iceland in May is manageable and worth it, we mean it with full knowledge of what genuine Nordic spring weather looks like. It is not a warm trip. It is not a predictable trip. But it is one of the more honest ways to experience a country that so many people see only through the filter of its July tourism machine.

The Iceland of May is quieter, wilder, and closer to the place it actually is most of the year. The waterfalls are louder. The roads feel like yours. The landscape is still in the process of becoming green, which means you catch it mid-transformation — snow still on the peaks, lupines just beginning in the south, light that does not quite know when to stop. If you are already considering Iceland in May, our advice is simple: book it, pack properly, and slow down more than you think you need to.
