Iceland in May

May is the value pick of the year. You get near-endless daylight, nature waking up, puffins and boat tours back, and roads opening up — all before summer pricing and summer crowds arrive. If you can travel in May, do.

What is the weather and daylight like in May?

Daylight is enormous. You start the month near 17 hours and finish close to 20, with long, lingering twilight on either side — by late May true darkness barely happens, which is why aurora season ends here. Plan to use the long evenings; sites stay lit until very late.

Temperatures rise to around 10°C high and 3°C low in Reykjavík, the mildest it has felt since autumn. Conditions can still flip to wet and cold, and snow lingers in the interior. Check Veður.is before committing to longer drives.

What is open and what is closed in May?

The Highlands and F-roads are still closed for most of May. They typically open mid-to-late June depending on snowmelt — see when Iceland’s F-roads open in 2026 and the live road.is status. Late May sometimes sees the first F-roads open, but do not build a plan on it.

Natural ice caves are closed. In exchange, the summer-season infrastructure starts: Jökulsárlón amphibian boat tours begin, whale-watching ramps up, and more rural guesthouses and restaurants reopen for the season.

The whole coastal Ring Road and the popular regions are fully accessible.

What should you actually do in May?

This is when green returns. Lupines have not peaked yet, but the landscape shifts from brown to alive, and waterfalls run full from snowmelt. The South Coast and Golden Circle are superb and far quieter than they will be in July.

Puffins are settled at southern colonies — Dyrhólaey, Vestmannaeyjar, Borgarfjörður eystri — through August; see where to see puffins in Iceland. Boat tours at Jökulsárlón and whale watching from Reykjavík or the north are both back on.

What should you avoid in May?

Do not plan a Highland or F-road trip — the interior is still closed, and attempting a closed F-road is dangerous and illegal. Do not come expecting aurora; the nights are too bright. And do not under-pack: 10°C in wind and rain still demands real layers and a waterproof shell.

How are crowds and prices in May?

May is the sweet spot. You get long days, mild weather, returning wildlife and boat tours at mid-shoulder prices, before the June–August surge in both crowds and cost. Book whale watching and any popular guesthouses ahead, but expect noticeably better value than peak summer.
