The Air District is asking the public to not burn wood in their fireplaces, woodstoves, or outdoor fire pits through the New Year’s holiday to keep air quality from becoming unhealthy.

The Air District is issuing a Spare the Air Alert for today, Sunday, December 8, which bans burning wood, manufactured fire logs or any other solid fuel, both indoors and outdoors. Regional wood burning and easterly winds transporting air pollution into the Bay Area from the Central Valley have contributed to high overnight concentrations of fine particle pollution and unhealthy air quality. Although light northerly winds will bring some improvement later in the afternoon and evening, parts of the Bay Area will still experience unhealthy air quality throughout the day. Breezier northeasterly winds will bring more substantial improvement in air quality for Monday.

San Francisco County rests at the northern end of the San Francisco Peninsula, bounded by San Mateo County in the south, the Pacific Ocean to the west, San Francisco Bay to the east, and the Golden Gate Bridge to the north. Three San Francisco County representatives sit on the Air District’s Board of Directors.
Climate
Because most of San Francisco's landscape is below 200 feet, the marine layer flows across most of the city, creating a cool and windy climate. The southeastern portion of the county, however, tends to be warmer and sunnier, with fewer foggy days. In the winter, average daily temperatures are mild overnight and moderate during the day, while summertime temperatures tend to remain moderate throughout the season. The highest wind speeds are focused along the western coast and generally mild throughout the county. Rainfall averages about 20 inches per year, with the highest amounts reported on the western coast.

Air Quality in San Francisco County
Ozone and fine particle pollution, or PM2.5, are the major regional air pollutants of concern in the San Francisco Bay Area. Ozone is primarily a problem in the summer, and fine particle pollution in the winter.
In San Francisco, ozone almost never exceeds health standards and PM2.5 only exceeds the national standard once or twice each year, generally. Being surrounded by water on three sides keeps temperatures within a narrow range, whereby winter low temperatures rarely reach freezing and summer high temperatures stay well below levels where ozone would form and become unhealthy.
