The Air District is issuing an air quality advisory due to smoke from the Somersville brush fire in Antioch. Smoke from this brush fire is expected to impact air quality in eastern Contra Costa County on Wednesday evening. Conditions can change rapidly and the amount and location of smoke at ground level is hard to predict. The public can check for real-time smoke pollution levels in their local area with the U.S. EPA’s Fire and Smoke Map. The Air District will continue to monitor conditions to see if impacts will continue on Thursday. Smoky, hazy skies may be visible, the smell of smoke is possible and air quality may become unhealthy as of Wednesday evening.

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。
