Speaking of which, what is the temperature like in September when we all drop by?
Despite the average of 20 degrees C which all wetaher outlets claim, it can range from 10 to 30 (with humindity), depending on Mother Nature's mood The best advice I can give is dress in layers. That way, if you're wearing a sweater with a tank underneath and it gets a litte sweaty one day, you'll be prepared. I would suggest to keep an eye out to the long-range forcaset on The Weather Network's Website for Montreal, and you'll get a good idea of what's in store for this year!
And congrats to all with anniversaries!
