Forecast Discussion:
A PM2.5 High Pollution Advisory is in effect for Maricopa County on Saturday. Stagnant conditions and strong temperature inversions will hinder built-up pollutants from dispersing out of the valley. Levels are expected to be highest in the early morning and late evening hours as fireplace/firepit activity increases.
PM2.5 will remain elevated after Saturday with stagnant overnight conditions persisting. During this time of year, it is not abnormal to see an increase in particulate matter over the weekends as we approach the holiday season.
Currently, no rain is in the forecast. Conditions will remain dry for at least another week.
If you are concerned about air quality this weekend, we recommend using our hourly graphs above to help you plan out your day. Around midday, air pollution levels will be the lowest.
Have a great weekend and we'll see you next week.

Ozone and Your Health
People most vulnerable to the impacts of air pollution include children, older adults, adults exercising outdoors, people with heart or lung disease, and those suffering from asthma and bronchitis. Exposure to ozone can increase the number and severity of asthma attacks, cause or aggravate bronchitis or other lung disease, and reduce the body's ability to fight infection. Symptoms may include itchy eyes, nose and throat, wheezing, coughing, shortness of breath, chest pain, and upper respiratory issues | View Ozone Fact Sheet >
Please help reduce ozone by doing one or more of the following:
- Drive as little as possible, carpool, use public transit or telecommute
- Re-fuel your vehicle in the evening
- Avoid waiting in long drive-thru lines, if possible
- Use low-VOC (Volatile Organic Compounds) or water-based paints, stains, finishes and paint strippers - delay big painting projects
- Make sure containers of household cleaners, garage and yard chemicals, and other solvents are sealed properly to prevent vapors from evaporating into the air
