The EPA Fire & Smoke Map displays the most current and comprehensive information on wildfires, smoke and air quality -- all in one map. You'll see air quality readings from around the region from both regulatory air monitoring stations and the most accurate readings from crowd-sourced, portable air quality sensors.

Currently, Sacramento County is not affected by wildfire smoke. When smoke impacts the county, this page will be updated.
Effects of Wildfire Smoke
Wildfires are now a regular occurrence in California and can happen at any time of the year. Smoke from these wildfires often impacts the Sacramento Region. The amount of smoke and which areas are impacted is largely dependent on wind direction and can change throughout the day. Smoke is unhealthy to breathe. If you smell smoke, you are advised to remove yourself from the area or go indoors. For more information on the health effects of wildfire smoke, visit the

Wildfire Smoke Information and PM 2.5 Monitor Map
The PM 2.5 Monitor Map is activated on SpareTheAir.com when a wildfire smoke episode is anticipated or occurs. This map provides EPA's NowCast PM 2.5 levels at all regional monitors, including any temporary monitors placed and brought online by Sac Metro Air District, another air district or CARB.
Real-time Air Quality Readings
Real-time air quality readings are derived using EPA's NowCast algorithm, which uses longer averages during periods of stable air quality and shorter averages when air quality is changing rapidly, such as during a fire. NowCast allows current conditions maps to align more closely with what people are actually seeing or experiencing.
Free Air Quality Mobile App
Choose a link below to download the free Sacramento Region Air Quality app. The app displays EPA's NowCast for each monitoring site in the Sacramento Region. Push notifications for wildfire smoke alerts are also available through the app.
If you are a school, business or public agency, follow the 5-Step Plan along with the Air Quality Action Charts below to help you make decisions that will help keep students, employees and residents as safe as possible during smoky days.

After the devastating wildfire season in 2018, Assembly Bill 661 (K. McCarty, 2019) was signed into state law. The legislation mandates the Sac Metro Air District develop a Wildfire Smoke Air Pollution Emergency Plan in full collaboration with the Sacramento County Health Officer and in consultation with other agencies - local emergency services offices, school districts, the Sacramento Planning agency and the California Air Resources Board (CARB). The plan will serve as an information resource for Sacramento schools, local agencies, businesses and the public during wildfire smoke air pollution emergencies. The plan specifically addresses these main elements:
The plan will be finalized and brought before the Sac Metro Air District Board for adoption in Summer 2022. Tools available now for use include Air Quality Action Charts and other helpful outreach flyers (see above). Annual summaries of Emergency Plan efforts submitted to AB 661 author, Assemblymember Kevin McCarty, are also available:

As part of the Emergency Plan development process, the Sac Metro Air District performed a survey of business, public agency and non-profit sectors in Sacramento County to find out how wildfire smoke events impact them and how they respond to protect their employees from excess exposure to smoke.

Social media is a great way to stay informed during a wildfire smoke episode. Here are some resources to follow.
During a wildfire smoke episode, the National Weather Service typically includes information on smoke in its robust daily forecast discussions. These forecasts incorporate wind direction and strength in addition to other atmospheric conditions that impact smoke transport.
Sac Metro Air District's daily air quality forecast also takes smoke modeling into consideration during episodes. This includes forecasting PM 2.5 levels during periods of concern in addition to factoring in wildfire smoke's impact on ground-level ozone formation.
There are several non-regulatory low cost sensor tools to access real-time air quality information during a wildfire smoke episode, PurpleAir is one of those tools. The following is a map showing the locations of all PurpleAir's and their associated real-time air quality information. Google Chrome or Microsoft Edge browsers are recommended for viewing this content.
Wildfire smoke includes particulate matter (PM). PM can be
directly emitted, as with fires, or it can form in the atmosphere
from reactions of gases such as nitrogen oxides. PM from wildfire smoke can cause serious health impacts.
The size of particles is directly linked to their potential
for causing health problems. Small particles (known as PM 2.5 or fine
particulate matter) pose the greatest problems because they bypass the body’s
natural defenses and can get deep into your lungs and potentially your
bloodstream. Exposure to such particles can affect both your lungs and your
Sac Metro Air District monitors PM 2.5 concentrations at several sites throughout Sacramento County.
Long-term exposure to particulate pollution can result in
significant health problems including:
Short-term exposure to particulate pollution can:
Even if you are healthy, you may experience temporary
symptoms, such as:
