The Air District is encouraging residents to prepare for potential smoke impacts this summer to protect their health in the event of widespread unhealthy air quality.
The Air District and Alameda County District Attorney Ursula Jones Dickson filed a joint civil lawsuit against Radius Recycling, formerly Schnitzer Steel Industries, for air quality violations related to the fire at the company’s facility in West Oakland on August 9-10, 2023. In addition, previous enforcement actions by the Air District and the district attorney required Radius Recycling to install new equipment that has eliminated hundreds of tons of air pollution and reduced cancer risk by 84 percent since 2022; today the Air District finalized the operating permit for this important equipment.
The Air District is lifting an air quality advisory for the Bay Area due to wildfire smoke that was originally scheduled to last through today, Monday, July 14. Over the weekend, smoke from the Butler and Green wildfires had been moving down the Sacramento Valley and impacting air quality in portions of the Bay Area. However, as of Monday morning, the Bay Area is experiencing strong onshore winds, and smoke has remained mostly outside of the region. Air quality has been in the Good Air Quality Index category. Moderate onshore winds are expected to continue into Tuesday, keeping the smoke outside of the Bay Area. As the week progresses, these onshore winds will turn southerly in northern California, and this also is expected to keep the smoke from moving towards our region.

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。
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。
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。
