• FIRE OUT BY 4 PM
All General Outdoor Burns must begin after 9 am and be fully extinguished by 4 pm, unless your local fire department has granted an extension. Air inversions tend to break up by 9 am. Waiting until after 9 am to ignite your burn lets the smoke disperse better. Afternoon winds are also typical in the spring. So for safety reasons, your fire MUST BE completely dead out -- NO SMOKE AT ALL -- by 4 pm. Additionally, smoke dispersion is poor after sunset, so a fire left smoldering overnight can cause smoke to build up, bothering neighbors and adding to Valley pollution.
