What makes Jaffray’s weather different from nearby towns?
Jaffray sits in the Elk Valley at the edge of the Rocky Mountain Trench, so its weather patterns often blend mountain influences with prairie spillover from Alberta. That means you’ll see bigger temperature swings than in Cranbrook or Fernie, especially in spring and fall. If you’re checking Kimberley BC weather or Fernie weather for comparison, note that Jaffray tends to be slightly drier and a few degrees warmer on average.
