I hadn't read about the extreme heat in Vancouver, unbelievable 49 degrees sounds more like Australia 
We were in Vancouver a few years ago and chatting to a waitress she told us that they had one year when it rained every day from September until early into the following year. A lovely city and far more temperate than other parts of Canada, it seems to have the same sort of rainfall similar to Seattle in the US, not that far down the coast. Although clearly not at the moment, it was very green when we were there, maybe not the case right now, I agree Roses such high temperatures are unbearable and I wouldn't like to have to live in a country where they experience those, it confines those people to an indoor life as much as bad weather does. It hasn't been a good summer so far this year, I think here in the south we've come to expect that we will get a hot summer every year so this current weather we are experiencing is a lot chillier.
