In reply to Chris Craggs:
I had a week in June. It rained every day, though with the midnight sun, "day" is less meaningful, and got some very enjoyable climbing in between showers/storms. I almost drowned on Gandalf, but by the time I'd finished yelling "I think we should go down", the gales had blown the rock bone dry again.
Generally, if it wasn't raining, it was howling with wind. I thought I was going to get blown off Glamtinden, which still had snow on it, and I was very cold, despite wearing two jackets and a pair of gloves. All in all it was pretty exciting
