氣候
聖拉蒙 (San Ramon) 和代阿布洛 (Diablo) 峽谷夏季溫暖，冬季涼爽，這很大程度上是因為它們遠離海水的調節作用，而且加州海岸山脈阻擋了海洋氣流吹進山谷。因靠近海洋和海洋氣流的影響，卡奇尼茲海峽 (Carquinez Strait) 氣候溫和。冬季，白天平均氣溫適中，夜間常有吐爾霧(Tule fog)。夏季平均氣溫通常夜間溫度適中，白天溫暖，西部海岸較為涼爽，常伴有較強風速。區域的風速一般較低，通常從西北往東南方向吹。但是卡奇尼茲海峽附近各縣的北部，午後常有陣風。整個縣的年降水量平均在 18 到 23 英寸之間。
康特拉科斯塔縣 (Contra Costa County) 的氣候還受到區域性灣區氣候的影響。
康特拉科斯塔縣的空氣品質
臭氧和細懸浮微粒污染（即 PM2.5）是影響舊金山灣區的主要區域性空氣污染物。臭氧問題主要發生在夏季，細懸浮微粒污染主要發生在冬季。
在東灣山脈西部的康特拉科斯塔縣，臭氧和 PM2.5 不常超過健康標準。舊金山灣區冬季氣溫在冰點以上，夏季最高氣溫在 100 華氏度以下。
在康特拉科斯塔縣東，夏季午後氣溫經常接近三位數，致使臭氧水平超過健康標準。冬季，PM2.5 從中央谷地通過卡奇尼茲海峽向西移動，加上木材煙霧，超過了健康標準。
