Air District extends air quality advisory for wildfire smoke through Monday
六月 23, 2025

The Air District is extending an air quality advisory due to wildfire smoke from Canada and Alaska in the Bay Area through Monday, June 23. Smoke from various wildfires in western Canada and in Alaska is expected to continue to impact air quality in the Bay Area on Monday. 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, the smell of smoke is possible and air quality may become unhealthy on Monday.

氣候

馬林縣西部海岸和南部常有涼爽的海洋空氣和濃霧。因為靠近海洋，這些地區的氣溫全年穩定。因為遠離海洋，馬林縣東面較為溫暖，少霧。距海洋較遠，使得海洋空氣在到達東部馬林城市之前升溫。整個縣的盛行風一般是西北風，西部海岸風速最高。山裡的年降雨量通常比灣區的大部分地方要高，平均在 37 到 49 英寸之間。該縣的大部分降雨發生在十一月到三月。

馬林縣 (San Francisco County) 的氣候還受到區域性灣區氣候的影響。

馬林縣的空氣品質

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。

沿著馬林縣海岸和馬林縣南部，來自太平洋的潔淨空氣幫助把空氣污染降到最低。在馬林的其他地方，偶爾才會出現臭氧問題，但丘陵地形和冬季較冷的氣候把 PM2.5 鎖在地表附近，致使空氣品質超過健康標準。
