Weather in Iceland in May: A Traveler’s Guide 🌤️❄️

May marks the beginning of Iceland’s shoulder season, offering a delightful mix of spring’s thaw and lingering winter charm. For travelers, this month is ideal for experiencing milder temperatures, longer daylight hours, and fewer crowds compared to peak summer. Here’s what you need to know about Iceland’s weather in May to plan your trip effectively.

🌡️ Temperature and Climate

In May, Iceland transitions into warmer weather, though “warm” is relative in this Arctic nation! Average temperatures range from 3°C to 9°C (37°F to 48°F). Coastal areas like Reykjavík are slightly milder, while inland and highland regions remain cooler.

  • Daytime highs: ~9°C (48°F)
  • Nighttime lows: ~3°C (37°F)
  • Rainfall: Expect 40–60 mm of precipitation, with rain more common than snow.

May is one of the driest months in Iceland, but sudden showers are still possible—pack a waterproof jacket! For a deeper dive into Iceland’s climate patterns, check our Iceland Climate Guide.

☀️ Daylight Hours

One of May’s biggest perks is the rapidly increasing daylight. By mid-May, Iceland enjoys 18–20 hours of daylight, with the sun setting around 11 PM. This extended twilight, known as the “midnight sun”, begins in late May, offering surreal golden-hour landscapes.

� What to Pack

  • Layered clothing: Thermal base layers, fleece, and a windproof outer shell.
  • Waterproof gear: Raincoat, sturdy hiking boots, and quick-dry pants.
  • Accessories: Gloves, a warm hat, and sunglasses (for glare from snow or water).

🌋 Best Activities in May

  1. Road Trips: The famous Ring Road (Route 1) becomes more accessible as snow melts.
  2. Waterfalls: Dynjandi and Seljalandsfoss are at their most dramatic with spring runoff.
  3. Wildlife Watching: Puffins return to coastal cliffs (best spots: Dyrhólaey or Látrabjarg).
  4. Hot Springs: Less crowded than in summer—try the Blue Lagoon or hidden gems like Reykjadalur.

⚠️ Travel Tips

  • Road conditions: Most F-roads (highland routes) remain closed until June. Check Road.is for updates.
  • Northern Lights: By May, the aurora season ends due to bright nights. For aurora hunting, visit earlier—see our Iceland in April guide.
  • Book ahead: Popular tours (e.g., glacier hikes or whale watching) fill up fast as tourism picks up.

📅 Comparing May to Other Months

  • Warmer than April: Less snow, more greenery.
  • Less crowded than June–August: Better prices for accommodations.
  • More stable weather than autumn/winter: Fewer storms.
