"Traditional worldcon dates" is exactly the same thing. Whose tradition? Who cares? Certainly not Aussie fans, 90% of whom never attend a worldcon outside Australia.
Where have the last several Worldcons been run? Oh, in the Northern hemisphere. The US-preferred traditional dates work fine for other Northern hemisphere cons. It totally makes sense for other worldcons to stick with US tradition when there is no downside for them. Would anyone want Glasgow to hold a con other than in summer? I doubt it.
Winter/early spring dates can be okay for a local con here that's in one building, but worldcons are long and spread over an area. Walking back to the Hilton from the Crowne Plaza at 2am was predictably nasty. October/November would have been lovely. Why would anyone choose "traditional" Northern hemisphere dates that pretty much ensure crappy weather here for a Melbourne Worldcon? Tradition is an appalling answer that basically amounts to "because that's what US SMoFs expect".
