What it means for you
Whether you're thinking of moving, gardening or travelling.
🏠 Living here
Comfortable year-round — sunny, dry summers and mild, wet winters. Heating is modest; AC is rarely necessary.
🌱 Gardening
Cool-season vegetables, stone fruit, berries and hops excel. Wine grapes do well at the warmer end.
✈️ Travel
Late spring through early autumn is the pristine window — warm, dry, sunny. Winter is wet but never brutal.
