While weather is never a sure thing, usually snow doesn't arrive until October. Right now, the weather is sunny and cool. September is usually one of the most pleasant months ... cool nights and sunny days. It can (and has) dipped to 0C at night, and be in the 20's in the afternoon.

which is the highway cam that actually points to the Freedom Road Series #1 cache.
Weather reporting (finding forecast and conditions) on the web can be problematic as the readings can be misleading. The reporting stations are a Williams Lake and Bella Coola, both of which are a long ways away (in different directions) and have distinctly different environmental situations.
After mid-October, there is a greater likelihood of weather concerns.
Again, right now there are perfect caching conditions: cool weather, lots of sunshine, no bugs, light traffic. It doesn't get much better than that.
