Wind Information

Wind direction is critical for a good or bad day in the saddle. Winds often flow up from the south and push west or east.

In Alberta - Chinook winds and Alberta weather

Having the wind with you can mean an extra 10km. On the flip side, a strong headwind can mean a 10km day total. The common belief is that prevailing winds go West to East. But that is not true. Not on a bicycle. For example:
  • Wind direction in the Rockies change day to day
  • Chinook winds occur over the winter and die out around Calgary
  • Prairies wind either blows up southwest or southeast (ref)
  • The Great Lakes Region has wind going every which way (ref)
  • Wind generally flows South-West down the St Lawrence River (ref)
  • Maritime winds come up South-West (Boston's weather 2-3 days later)
