The map below is generated by PurpleAir. This grassroots organization relies on volunteers to allow air sensors to be placed on their businesses or homes. PurpleAir uses the same scale that the Environmental Protection Agency uses - the Air Quality Index scale - to compare and measure pollutants in the air.

The scale uses green for good, yellow for moderate, orange for unhealthy for sensitive groups, red for unhealthy, purple for very unhealthy and maroon for hazardous. The Air Quality Index above is also useful, but only monitors several County-wide sensors. Click here to learn more about AQI.

Today’s Burn Conditions

Stage 1 Fire Restrictions in Place


Under Stage 1 Fire Restrictions, no residential burning is allowed. Agricultural burns must have a Sheriff issued permit.

In Mesa County residential open burn seasons run from March 1 – May 30 (Spring Open Burn) and from September 1 – October 31 (Fall Open Burn).  The burn season within City limits is one month shorter.

Agricultural open burning is allowed year-round with a permit.

No Burn Advisory

If conditions warrant, a No Burn Advisory may be issued to protect the health of residents. When one is issued, restrictions are put in place on open burning or woodstove burning. Residents should note that woodstove burning restrictions do not apply to those who use a woodstove as a primary heat source.

Air quality is the state of air that promotes optimal health.  Air quality impacts how you live and breathe.  It can change from day to day, even hour to hour.  Mesa County Public Health is constantly monitoring air quality with forecast models, measurement tools and observation.  Our team utilizes this local data to inform and educate community members about current air quality conditions. This data, over time, helps shape local policies on clean air.

What impacts our Air Quality

We use a measurement system called AQI (air quality index) developed by the Environmental Protection Agency (EPA) to assign a numerical value to the air quality.  This system takes four major air pollutants into account, ground-level ozone, particle pollution, carbon monoxide, and sulfur dioxide.  The higher the AQI, the greater the level of air pollution.

Daily AQI Color


Levels of Concern Values of Index Description of Air Quality
Green Good 0 to 50 Air quality is satisfactory, and air pollution poses little or no risk.
Yellow Moderate 51 to 100 Air quality is acceptable. However, there may be a risk for some people, particularly those who are unusually sensitive to air pollution.
Orange Unhealthy for Sensitive Groups 101 to 150 Members of sensitive groups may experience health effects. The general public is less likely to be affected.
Red Unhealthy 151 to 200 Some members of the general public may experience health effects; members of sensitive groups may experience more serious health effects.
Purple Very Unhealthy 201 to 300 Health alert: The risk of health effects is increased for everyone.
Maroon Hazardous 301 and higher Health warning of emergency conditions: everyone is more likely to be affected.
