Why Climate Zone 2 Matters Here

Angwin's designation as Climate Zone 2 reflects a moderate maritime climate with mild summers and cool, wet winters, a factor our energy models account for when calculating your compliance margin.

Estimated from proximity to the nearest CEC reference station — we confirm the exact zone for your project's address before preparing your report.
