Protect your health when air quality is poor
When air is unhealthy, the best option is to reduce physical activity and stay indoors with doors and windows closed.
Drink lots of water to stay hydrated. Smoke can irritate your eyes and airways, cause cough, a dry scratchy throat, runny nose, trouble breathing, and irritate your sinuses.
When inside
Avoid behaviors that make air quality in your home worse:
- Set air conditioning units to re-circulate so you don't bring outside air in.
- Don't smoke, burn candles, or use incense.
- Don't use gas, propane, or wood burning stoves. Avoid frying or broiling meat.
- Avoid vacuuming.
Take precautions when outdoors
Minimize time outside as much as possible.
When you must go outside, don't rely on dust masks or bandanas for protection. They do nothing to protect against smoke particles.
Checking air quality conditions
The best source for up-to-date air quality information is the airnow.gov interactive map, which is updated hourly with readings from the Berkeley air monitor in Aquatic Park.
Searching "Berkeley" on the airnow.gov homepage returns air quality information for the greater Oakland reporting area, which does not always reflect local conditions here in Berkeley.
Use the Air District air quality index tracker to see how conditions have changed over time. This page provides a record of the hourly readings from air monitors around the Bay Area, including Aquatic Park.
Air Quality ratings
The Air Quality Index (AQI) provides guidance on who should take precautions when.

AQI Range |
Health Impact |
What to do |
|
Good |

Unhealthy for Sensitive Groups |
Air quality may pose risks to people with heart and lung disease, older adults, children, and pregnant individuals. |
Sensitive groups: Reduce prolonged or heavy exertion. It's OK to be active outside, but take more breaks and do less intense activities. Watch for symptoms such as coughing or shortness of breath. |
|
Unhealthy |
Everyone may begin to experience adverse health effects. Members of sensitive groups may experience more serious health effects. |
Sensitive groups: Avoid prolonged or heavy exertion. Move activities indoors or reschedule to a time when the air quality is better. |

Preparing before a bad air event
The most important thing you can do to prepare is to sign up for emergency notifications at acalert.org. This will ensure we can reach you in an emergency.
Steps for everyone
Other steps you can take to prepare for poor air quality:
- Know where to go.
Make a list of places you can go with clean, filtered air. - Weatherize your home.
Replace leaky windows and doors. Use caulking to seal the openings. - Gather supplies
Gather supplies you need to stay in your home while air quality is poor. See the CDC's website on personal health preparedness. - Get an air purifier for your home.
If you have an HVAC system, get a MERV 13 or greater filter. Otherwise, get a HEPA air purifier. The California Air Resources Board has information about selecting an air cleaning device. - Create a family emergency plan.
Before an emergency happens, sit down together and decide how you will get in contact with each other, where you will go and what you will do in an emergency. See FEMA's family emergency plan checklist.
Individuals with health conditions
If you have a health condition or belong to a group at high risk when air quality is poor, talk to your doctor in advance to create a personal plan for dealing with smoke.

- People who have heart or lung disease
- Older adults
- Children
- Pregnant individuals
