Iceland in Summer: Your Complete June to August Guide
What Makes Summer in Iceland Special
Summer in Iceland is a completely different country from winter. Temperatures hover between 10 and 20 degrees, the sun barely sets (if at all), and the entire island opens up. Highland roads that are buried under snow in winter become passable, puffins arrive in their millions, and whale watching season peaks. Festivals fill Reykjavik's streets, and the country buzzes with an energy that the darker months simply cannot match.
The downside? Everyone knows this. Summer is peak tourist season, and prices, crowds, and accommodation availability reflect that. Planning ahead is essential.
June: Midnight Sun and Puffins
June is arguably the best month to visit. The midnight sun reaches its peak around the summer solstice (21 June), giving you 24 hours of daylight. Puffins arrive at their nesting sites from late April, and by June the cliffs are alive with these charming birds.
Temperatures average 9 to 14 degrees. Most highland roads open in late June. The Westfjords become accessible. This is also the driest month statistically, though "dry" in Iceland still means carrying waterproofs.
July: Peak Season
July is the warmest month, with temperatures occasionally reaching 20 degrees in sheltered areas. Every campsite, tour, and guesthouse is operating at full capacity. Book accommodation months in advance.
Highlights include the midnight sun phenomenon at its most dramatic, full Ring Road accessibility, and the best conditions for hiking. Festivals like Verslunarmannahelgi (the August Bank Holiday weekend, which often starts in late July) bring outdoor concerts and celebrations.
August: Late Summer Magic
August brings slightly shorter evenings and the first hints of autumn. By late August, you might catch the first northern lights of the season, creating a unique crossover period where midnight sun gives way to aurora.
Berries ripen in the valleys, lamb is harvested, and the landscape takes on golden tones. Puffins begin departing by mid-August. Highland roads typically remain open until mid-September.
What to Pack for Summer
Even in summer, layering is essential. A typical summer day might start at 8 degrees with drizzle, warm to 15 degrees with sunshine by noon, and drop to 10 degrees with wind by evening. Pack:
- Waterproof outer layer (jacket and trousers)
- Fleece or insulating mid-layer
- Base layers (merino wool is ideal)
- Sturdy walking shoes (waterproof recommended)
- Sunglasses and sunscreen (the midnight sun is surprisingly strong)
- Eye mask for sleeping (essential if you are light-sensitive)
Summer Activities
- Glacier hiking: Available year-round but most pleasant in summer.
- Whale watching: Humpback whale season peaks June to August.
- Kayaking: Sea kayaking in the Westfjords and Eastfjords.
- Horse riding: Icelandic horse tours through lava fields and river valleys.
- Snorkelling and diving: Silfra fissure in Þingvellir is crystal-clear year-round but more comfortable in summer.
Budget Considerations
Summer is the most expensive time to visit. Expect to pay 30 to 50% more for accommodation compared to shoulder season. Car rental prices double. Camping is the most cost-effective accommodation option if you have the gear.
