氣候
半島西部海岸以涼爽、多霧的天氣為主，尤其是在夏季。夏季的日平均氣溫，沿西部海岸較為溫和，該縣東面相對溫暖。冬季，全縣的日平均氣溫溫和舒適。微風，最高風速集中在西部海岸。海拔較低處的年均降雨量大約在 20 到 25 英寸之間，聖克魯斯山 (Santa Cruz Mountain) 的年均降雨量最高可達到 36 英寸。
聖馬特奧縣 (San Mateo County) 的氣候還受到區域性灣區氣候的影響。
聖馬特奧縣的空氣品質
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。
在聖馬特奧縣，臭氧幾乎從沒有超過健康標準，PM2.5 通常每年只有一天會超過國家標準。太平洋的新鮮海洋空氣經常飄過海岸邊的丘陵，到達聖馬特奧縣。在冬季，PM2.5 會從灣區的其他地方飄到聖馬特奧縣，加上木材焚燒的煙霧，可能會導致 PM2.5 濃度升高，但很少能超過健康標準。
資源團隊
聖馬特奧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。
