Ohio Air Quality Index Forecasts

To see a forecast for an Ohio city, click on a link below:

Air quality forecasts are provided by State and local agencies, using U.S. EPA's Air Quality Index (AQI), a uniform index that provides general information to the public about air quality and associated health effects. The AQI is an index for reporting  daily air quality. It tells you how clean or polluted your air is, and what associated health effects might be a concern for you. U.S. EPA has established national air quality standards to protect public health for several pollutants.

AQI Forecasts Can Help You Protect Yourself

You’re exposed to pollution any time you breathe polluted air. But when you exercise, do yard work or other strenuous activities that increase your breathing rate, you take more pollution into your lungs. You can reduce your exposure by using AQI forecasts to help you plan your day. When the forecast calls for elevated levels of pollution, protect your health by reducing your exposure – especially if you are in a sensitive group.

Take it a little easier. You can cut back on strenuous activities (for example, go for a walk instead of a jog). Or reschedule strenuous activities for times when air quality is expected to be better. It’s a small change that can help you protect your lungs and heart.

Where Can You Find Your Local AQI Forecasts?

  • Many local television stations, radio stations and newspapers carry local AQI forecasts.
  • You also can find your local forecast by logging on to U.S. EPA’s AIRNOW website at www.airnow.gov

Groups Sensitive to the Effects of Air Pollution

  • Particle pollution — People with heart or lung disease (such as asthma), older adults and children.
  • Ground-level ozone — People with lung disease (such as asthma), and children and adults who are active outdoors.

Note: Data in these reports are always referenced to Eastern Standard Time (EST). Air Quality Index reports are updated several times during a day at regular intervals (generally 15 or 30 minutes past the hour or hourly from 8 a.m. - 10 p.m.).

Disclaimer: These reports present the data in "RAW" form, meaning that the data you see are exactly what was collected electronically from each pollution monitor several times during each day. It is important to remember that "RAW" data are never considered valid until verified by Ohio EPA and Local Air Agency personnel.

The data in these reports have neither been validated nor quality assured by state or local air monitoring agencies. These data may change and are not considered official until they have undergone a quality assurance/quality control (QA/QC) review.

Odd data are suspected invalid due to possible equipment trouble or telemetry problems.
