Short answer

Norwegian summers, from June to August, are mild and light, with July averages of nearly 18 °C in Oslo and over 12 °C in Tromsø. Warm days can reach 25 to 30 °C in the south and inland valleys, while the coast gets more rain and wind. North of the Arctic Circle, the sun stays up all night.

Why

  1. In the 1991–2020 normal, July averages 17.7 °C in Oslo, 15.6 °C in Bergen and 12.3 °C in Tromsø, counting day and night.
  2. MET Norway measured the highest temperature of summer 2026, 34.2 °C, at Nesbyen in Buskerud on 15 July 2026.
  3. Visit Norway says the nights never get really dark anywhere in the country from late June to early August.

Details

Visit Norway says summer weather can be fairly stable but can still surprise you. On the west coast, rain increases through the summer: Bergen's normal is 132 mm in June, 158 mm in July and 208 mm in August. In southern Norway, sea and lake water usually reaches 18 °C or more.

Tip

Bring waterproof and windproof clothing and a wool layer for hikes and boat trips, and pack sunscreen and a swimsuit too.

What may differ

The far north is cooler, with a June normal of 9.4 °C in Tromsø. Single summers can also differ: summer 2026 ended 0.5 °C above normal across Norway, although July 2026 was 0.1 °C below normal.
