What it means for you
Whether you're thinking of moving, gardening or travelling.
🏠 Living here
Long, cold winters and warm but not hot summers. Heating dominates. A strong outdoor culture in summer to balance the long indoor winter.
🌱 Gardening
A ~5-month growing season — hardy apples, maples, root vegetables, brassicas. Heat-loving crops are marginal without season-extension.
✈️ Travel
Summer is the practical window; autumn brings spectacular foliage in many areas. Winter is for skiing and ice — beautiful but brutal.
