索拉諾縣北面接壤納帕縣和優落 (Yolo) 縣，東面毗鄰沙加緬度縣 (Sacramento County)，南面連接聖帕布洛灣。空氣局只對該縣的西南部有管轄權，包括瓦列霍 (Vallejo) 和菲爾費爾德 (Fairfield)。索拉諾縣有一名代表進入空氣局董事會。
氣候
在夏天和降雨季期間，近岸處氣壓高，加上中央谷地的高溫低氣壓，幾乎每天都推著海洋空氣往東穿過卡奇尼茲海峽 (Carquinez Strait)。沿岸處的氣溫和內陸氣溫適中。冬季，夜間涼爽，白天氣溫適中；夏季，夜間溫度適中，白天溫暖。該縣南部沿著卡奇尼茲海峽的地方，午後常有西風。沿岸附近的年降雨總量在 13 英寸左右，內陸菲爾費爾德的年降雨總量是 22 英寸。
索拉諾縣 (Solano County) 的氣候還受到區域性灣區氣候的影響。
索拉諾縣的空氣品質
臭氧和細顆粒物污染（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，細顆粒物污染主要發生在冬季。
夏季，索拉諾縣大部分地區受到從卡奇尼茲海峽 (Carquinez Strait) 吹來的盛行西風影響，風裡挾著來自太平洋和聖帕布洛灣涼爽的海洋空氣向東，稀釋並降低了當地的臭氧濃度。 但是，在洋流較弱或不存在的時候，臭氧濃度每年可能會有幾天超過健康標準，主要集中在薩松市東部。
在索拉諾縣，冬季盛行的東風把中央谷地的空氣污染傳送到這裡，會使 PM2.5 的濃度升高到健康標準以上。在寒冷無風的冬天夜裡，當地居民焚燒木材也會造成顆粒物濃度升高。
資源團隊
索拉諾縣的愛惜空氣資源團隊在當地社區倡導降低空氣污染的方式。
