Berkeley’s air quality was unhealthy for sensitive groups Wednesday, according to a tweet from the city of Berkeley.

As of press time, the air quality index is 134 out of 500. Sensitive groups at this air quality level include people with heart or lung disease, older adults, children and pregnant individuals, according to the city of Berkeley’s website. Members of the public can still be active outside but are advised to take breaks and watch for symptoms, including coughing and shortness of breath.
