New Yorkers got an unwelcome mid-summer twist on Tuesday as state officials urged people to stay inside during a full-day ozone alert blanketing the city and Long Island. The Air Quality Health Advisory runs from 11 a.m. to 11 p.m. and is aimed at protecting residents most vulnerable to breathing problems in hot, sunny weather. Officials said the air will be at its worst from this afternoon into the early evening.
State issues ozone advisory
The New York State Department of Environmental Conservation and the State Department of Health issued the Air Quality Health Advisory for Tuesday, July 14, after forecasters predicted that ground-level ozone would push the Air Quality Index into the "unhealthy for sensitive groups" range. The advisory covers all five boroughs, along with Rockland, Westchester, Nassau and Suffolk counties, according to DEC.
Ozone peaks in afternoon, not always visible
Ground-level ozone forms when sunlight triggers a chemical reaction between nitrogen oxides and volatile organic compounds from sources like vehicle exhaust and industrial emissions. Levels tend to spike in the late afternoon and early evening, which makes long outdoor workouts, sports or heavy physical labor riskier today for children, older adults, pregnant people and anyone with asthma or other heart and lung conditions, as noted by Time Out New York. You may not see or smell much, but your lungs will notice.
Simple steps to lower your risk
Officials are asking residents to take pollution‑reducing and energy‑saving steps: use mass transit or carpool, combine necessary car trips, turn off unused lights and delay energy‑intensive chores like running dishwashers and dryers until after 7 p.m. The state also recommends setting air conditioning near 78 degrees when cooling indoor spaces. Those suggestions come from the state advisory; if you do not have reliable AC, the city's Cool Options map and Cooling Center Finder can help you locate air‑conditioned public spaces. For more detail, see the state advisory and the city's cooling finder at DEC and Cool Options NYC.
Ozone levels usually drop after dark, so conditions are expected to improve later this evening. Check current readings at AirNow or the DEC forecast before planning outdoor time, and contact a health provider if you experience chest pain, shortness of breath or persistent coughing, as advised by Time Out New York.
