Each year, from April through October, warmer temperatures and strong sunlight can lead to higher formation of ground-level ozone —a harmful air pollutant that affects everyone, especially children, older adults, and people with respiratory conditions. On hot, sunny days, ozone pollution can rise to unhealthy levels. But you can help reduce ozone and protect your health:
- Stay informed – sign up for Air Quality Alerts for your area
- Track local conditions – Download the free AirNow app and track the Air Quality Index
- Drive Less – Combine errands, carpool, take transit or bike when possible
- Avoid vehicle idling – Especially during school pick-up and drop-off
- Rethink yardwork – Use gas-powered equipment after 7 p.m. or upgrade to electric lawn equipment
Two certified monitors keep track of the ozone levels in the area – one located in Manitou Springs and at the other located at the United States Air Force Academy. With the hottest part of the year still on the horizon, now is the time to take simple, voluntary steps to help protect our region’s air.
When the Colorado Department of Public Health and Environment issues an Ozone Action Day Alert, residents are encouraged to take action to reduce ozone-forming emissions. Even small changes—like upgrading to electric yard tools, avoiding idling, or skipping a short car trip—can make a big difference in helping to lower pollution levels on high ozone days.
Stay Informed All Season Long
The CDPHE Air Pollution Control Division is resuming its daily email updates for the 2025 ozone pollution season. With ozone pollution generally peaking during the summer, the division issues daily forecast emails every year to help Coloradans plan ahead. These email alerts go out from May 31 to Aug. 31. If forecasts show that day or the next may exceed National Ambient Air Quality Standards, the email will say an “Ozone Action Day Alert” is in effect. To receive ozone alerts by email notification, subscribe to receive email alerts from CDPHE.
