Mediterranean Climate Benefits

Sacramento's Mediterranean climate (like Spain, Italy, and Greece) is ideal for gardening: wet, mild winters and dry, hot summers create a long growing season. Unlike desert cities, Sacramento doesn't get extreme heat (rarely over 105°F) and has higher humidity. The distinct rainy season (November-March) provides natural irrigation when summer crops are dormant.
