Gordon, I was on a cruise in Norway two weeks ago, and it wasn't summery even for Norway. The farthest north we went was Geirangerfjord. It wasn't as cold as 3 Celsius (37 F), but there was still snow on the mountains. Some people who went off on an excursion reported that people were still skiing.
It rained for a good deal of the week, though - amazingly! - it was sunny in Bergen. Scarcely recognized the place.
