The Air District is issuing an air quality advisory due to wildfire smoke from the Moon Complex fire in Oregon for tonight, September 27, and tomorrow, September 28. Smoke from the Moon Complex in southwestern Oregon has been drifting southward offshore over the past few days and has mixed with the marine layer that is moving onshore over the Bay Area this Saturday evening and Sunday. 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. Smoky, hazy skies may be visible, and the smell of smoke is possible.

氣候
因為舊金山的大部分地勢低於 200 英尺，海洋氣流流過城市的大部分地區，形成涼爽多風的氣候。而該縣東南部則較為溫暖，陽光較為充足，霧天較少。冬季，每日平均氣溫夜間適中，白天溫和；夏季，整個季節的氣溫都較為溫和。最高風速都發生在西部海岸，縣內一般為輕風。每年的降雨量平均在 20 英寸左右，最高降雨量發生在西部海岸。
舊金山縣 (San Francisco County) 的氣候還受到區域性灣區氣候的影響。
舊金山縣的空氣品質
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。
在舊金山，臭氧幾乎從沒有超過健康標準，PM2.5 通常每年只有一兩次超過國家標準。舊金山三面環水，使這裡的氣溫變化較小，因此冬季低溫很少達到冰點，夏季高溫也在形成臭氧及達到不健康標準的水平以下。
