Norwrgian airport operator, Avinor, notes that both domestic (+5.2%) and international (6.7%) traffic increased during the month, during which many airports set new passenger records.
Oslo Airport welcomed almost 2.7 million travellers (+9.4%) through its doors in July, ensuring its busiest ever summer month.
Bergen also saw significant growth with an increase of 4.9% compared with the corresponding month a year ago.
Bergan's airport director, Aslak Sverdrup, notes that the continued upturn in traffic shows that his gateway needs its new terminal, which is due to open next week.
"We are delighted with the excellent development in traffic this summer, " says Sverdrup.
"These figures show how necessary it is for us to open the new terminal. It is important for the region to have an airport that runs smoothly without restrictions for those traveling from Bergen — and for anyone flying in to visit the city and our region.
"We are looking forward to welcoming everyone to a brand new airport."
Several of Avinor's minor airports in the districts also experienced double-digit growth in July, the healthy increases boosted by a record number of tourists.
The biggest winners were Røros (+40.3%), Stokmarknes (+37%), Svolvær (+26.7%), Leknes (+27.4%) and Sandane (+21.9%)
