May might be Iceland's best-kept secret. Almost 20 hours of daylight, puffin colonies in full swing, purple lupins carpeting the lowlands, and — crucially — the summer crowds haven't arrived yet. Prices are still shoulder-season, roads are clearing, and the landscape is vibrant green against snow-capped peaks. It's the sweet spot.

What You Can See
- Northern lights: No — too bright.
- Midnight sun: Nearly. Late May nights are bright twilight, not true midnight sun, but functionally it never gets dark.
- Puffins: Yes! Colonies at Látrabjarg, Dyrhólaey, Westman Islands, and Borgarfjörður Eystri are active.
- Whales: Excellent. Humpbacks, minkes, and dolphins common off Húsavík and Reykjavík.
- Wildlife: Birdlife at peak migration. Arctic terns nesting (watch your head). Seal colonies active.
- Landscape: The most colourful month — purple lupins, bright green moss, white snow on peaks, blue glaciers. Everything is saturated.

What to Pack
Lighter layers than winter — fleece, rain jacket, hiking boots. Add a sleep mask (essential) and sunscreen (the UV is stronger than you think). Swimsuit as always.

Budget Snapshot
Crowds & Pricing
Late shoulder season. Prices creeping up toward summer rates but still 15–25% below July peaks. Book accommodation 2–3 weeks ahead, especially for popular areas.
May is when Iceland's colour palette explodes. The lupins — those purple blankets that carpet every roadside, every hillside, every field — are in full bloom. Waterfalls that were frozen in January are now thundering with meltwater. The moss-covered lava fields are electric green. Snow still caps every peak, giving the landscape an alpine drama that fades by July.
And the light. Oh, the light. By late May, the sun sets around 11:30pm and rises before 3:30am — that's about 20 hours of daylight, with the in-between hours a luminous twilight rather than true darkness. You can drive the Ring Road at midnight with golden light on the mountains. You can photograph Kirkjufell at 11pm with nobody else around. A sleep mask is the most important thing in your luggage.
Puffins are the other May highlight. The colonies at Látrabjarg (Westfjords), Dyrhólaey (south coast), and Borgarfjörður Eystri (east) are bustling with returning birds. They're comically charming — waddling along cliff edges with beaks full of fish — and you can get remarkably close at some colonies. Late May through July is prime puffin season.
The only downside to May is that a few highland F-roads remain closed. If Landmannalaugar or Askja are on your must-see list, you may need to push to mid-June. But for the Ring Road and all the major attractions, May is arguably the single best month to visit Iceland.
Frequently Asked Questions
Is May a good time to visit Iceland?
May is one of the best months to visit. You get near-midnight-sun daylight, puffins, lupins in bloom, fewer crowds than summer, and lower prices. The only downside is that highland interior roads remain mostly closed.
Do you need a sleep mask in May in Iceland?
Absolutely. By late May, it barely gets dark — the sun sets around 11:30pm and rises before 3:30am. Without a sleep mask, you'll struggle to sleep, especially in accommodation without blackout curtains.
