The Yolo-Solano Air Quality Management District has issued an Air Quality Advisory for Yolo County and the northeastern portion of Solano County due to wildfire smoke from fires in Shasta and Siskiyou counties.

This advisory is in effect through July 11 unless otherwise extended or rescinded by the agency.

Smoke from multiple wildfires burning in Northern California is impacting air quality across the region. Depending on changing wind direction and wildfire activity, smoke impacts will vary between moderate to unhealthy levels in Yolo County and northeastern Solano County. Light northwesterly winds are carrying smoke into the region, though southerly/southwesterly winds forecast for Saturday and Sunday may help improve air quality.

Additionally, Friday, July 11, is a Spare the Air Day for the Sacramento region, including Yolo and northeastern Solano counties. Ozone levels are forecast to reach Unhealthy for Sensitive Groups throughout the Sacramento region.

Poor air quality from wildfire smoke has the potential to cause negative health impacts. Wildfire smoke contains very small particulate matter that is breathed deep into the lungs. If you see or smell smoke, you are breathing it. Everyone—especially children, older adults, pregnant individuals, and those with heart or lung conditions—should take steps to reduce exposure to smoke.

To reduce your exposure to smoke:

Check local air quality at fire.airnow.gov

Stay indoors and keep windows and doors closed

Limit outdoor activity, especially exercise

Avoid using fans that pull smoky air indoors (e.g., swamp coolers, whole-house fans)

Run your air conditioner, and set it to “recirculate” or “recycle” if possible

Avoid indoor pollution: don’t smoke, vacuum, fry food, or burn candles/incense

Use a HEPA air purifier to clean indoor air

Create a “clean room” with an air purifier where people and pets can shelter from smoke

Contact your healthcare provider if you or someone in your care experiences symptoms related to smoke exposure, such as repeated coughing, shortness of breath or difficulty breathing, wheezing, chest tightness or pain, palpitations, nausea or unusual fatigue or lightheadedness.

The Yolo-Solano Air Quality Management District’s mission is to protect human health and property from the harmful effects of air pollution.

As a public health agency, the District is responsible for safeguarding air quality and overseeing air pollution control in Yolo and northeastern Solano counties, including the cities of Dixon, Rio Vista, and Vacaville. For more information, visit ysaqmd.org.
