Field notes
Slightly drier and warmer than Seattle — fewer all-day rain days, hotter summers (July–August often 28°C+), more reliable sunshine June through September. Wet season runs October through May; ice storms 1–2x per winter are the recurring infrastructure event. Smoke from regional wildfires is the new August–September hazard.
