Why Climate Zone 12 Matters Here
As part of Climate Zone 12 (Central Valley), Sonora projects are modeled against very hot summers and cool, often foggy winters — which is why a report written for a different zone won't transfer directly.
Estimated from proximity to the nearest CEC reference station — we confirm the exact zone for your project's address before preparing your report.
