We went last in September, and found the weather to still be pleasant yet it was not crowded with tourists, even Granville Island had plenty of parking.
What is the cheapest time of year to travel to Vancouver? I'd like to vacation there but want to go in the slow part of the year.
Fall Winter, It really depends on what your willing to put up with because here on the coast during those months "ANYTHING GOES". Yes we get a lot of rain but is quite mild Temps compared to the rest of the country.
It's hard to say when is the cheapest if you are from here. But it is usually fairly nice from June through september, and it rains a lot in the winter. But it can rain anytime as well. If they do hotwire and priceline here, I'm sure you could find a deal. I guess it depends on what you want to do. The tourist trap stuff can be expensive, but there are tons of things to see and do for little money.
