It makes no sense to compare the summer of the northern coniferous forest zone to the summer of the tropical north of Australia or summer in the Mediterranean climate of southern Australia. There is a very clear and distinct summer season that lasts about 2-4 months between the 60th and the 70th latitudes. In fact, temperature-wise summer in the Nordic countries is very much like a typical summer in Britain. The more northerly location is compensated for by the much less oceanic climate. For instance, in London, UK, the the average daily maximum in July is 23 C, which is nearly the same as that in Tampere in July. The biggest difference between the climates of London and Helsinki is between the weather patterns in the winter. Helsinki is easily 10 C colder on average. But the summer temperatures are very similar.
