Iceland in August: Weather, What to Do, and Travel Tips
August is the last month of Iceland’s high summer — and one of the most rewarding for timing. Early in the month you still have near-endless light and all activities running; by late August, darkness returns and the first Northern Lights of the year become possible. The Bank Holiday Weekend (first weekend of August) is Iceland’s biggest party — expect full campsite occupancy across the country. Prices stay high through August, with a modest dip in the final week.

Best Activities in August

Highland drives — Landmannalaugar, Kjölur route, and Þórsmörk are all accessible in August. The colourful rhyolite mountains at Landmannalaugar are at their most vibrant with summer greenery. A 4WD vehicle is required for all F-roads.
Whale watching — Strong encounter rates continue through August. North Sailing in Húsavík and Classic Whale Watching in Reykjavík both operate daily. Adult tickets from approximately ISK 12,900 to ISK 13,900 as of 2026.
Puffin watching — Puffins depart the cliffs between mid-August and early September. Visit Dyrhólaey or Ingólfshöfði in the first two weeks of August for your best chance. By late August, most have left.

Events in August
Verslunarmannahelgi (Bank Holiday Weekend) — First Monday of August is a national holiday. The preceding weekend (Friday through Monday) is Iceland’s biggest social event of the year. The Þjóðhátíð festival in the Westman Islands (Vestmannaeyjar) is the centrepiece: held in a natural volcanic amphitheatre, it runs over 3 days with music, bonfires, and fireworks. Ferry from Landeyjahöfn south coast; festival tickets from approximately ISK 20,000 to ISK 30,000 per person as of 2026.
Reykjavík Gay Pride (Hinsegin Dagar) — Pride parade and week of events in early August. The parade itself (usually first Saturday of August) draws over 100,000 spectators in a city of 130,000. Free to attend along the route through central Reykjavík.
Reykjavík Culture Night (Menningarnótt) — Held the same Saturday as Gay Pride. Museums open late, outdoor performances across the city, and fireworks over the harbour at midnight. Free entry to most venues; a full evening out with no ticket cost.

Vatnajökull area: Fosshotel Glacier Lagoon (near Jökulsárlón) is the most convenient option for the glacier lagoon; from approximately ISK 35,000 per night in August as of 2026. Book months ahead.
Where to Eat in August
Reykjavík’s Hlemmur Mathöll food hall (near Hlemmur bus terminal) remains one of the best value dinner spots in the city — multiple vendors, fish tacos to Icelandic lamb stew, from approximately ISK 2,000 to ISK 3,500 per dish as of 2026.
Grillmarkurinn (Lækjargata 2a) for a sit-down dinner featuring quality Icelandic lamb — mains from approximately ISK 5,500 as of 2026.
In Húsavík, Gamli Baukur (Hafnarstétt 9) is the most popular waterfront option; fish dishes from approximately ISK 3,500 as of 2026 — reliably good before or after whale watching.
Northern Lights in August
The first Northern Lights of the season can appear from mid-to-late August as darkness returns. Nights must be properly dark (past twilight) for aurora to be visible — this happens from around August 20 in Reykjavík. Akureyri gets darkness back slightly earlier. Check vedur.is aurora forecast for cloud cover and KP index predictions simultaneously.
Tour operators typically begin their Northern Lights tours from around August 20–25. Arctic Adventures and Reykjavik Excursions run evening departures with resail guarantees from approximately ISK 9,900 as of 2026.
