New York City AQI planning guide

For New Yorkers, AQI becomes useful when it answers a practical question: is this just city background pollution, or enough to change today's outdoor time?

Live AQI and forecast

Current observations and forecasts come from the US EPA AirNow network. Current AQI is an area-level NowCast; local smoke shifts can still change conditions quickly.

Peak concern season

Jun-Sep

Heat, traffic, and occasional Canadian smoke drive the biggest AQI spikes.

Repeat-use trigger

Street-level commute

Platform waits and avenue walking can add up faster than the city average suggests.

Indoor priority

Apartment ventilation

Open-window apartments need a faster switch to filtered indoor air on smoky days.

Upcoming forecast

AQI 50

Good

8/17 - A cold front will pass through the region later in the day on Monday. Good air quality is expected due to mostly cloudy skies, northwest winds, and a chance of rain. 8/18 - Sunshine returns on Tuesday along with highs in the mid-80s and northerly flow. Levels of fine particulates rise to the good/moderate threshold, while ozone rises to the moderate category along the coast.

Using live AQI

AQI 34

Good

About 0.28 cigarettes per 24h at this reading.

Short outdoor activity is generally low risk when AQI stays in this range.

Proceed with normal outdoor activity.
Use the day to ventilate and prepare before worse conditions arrive.
Check tomorrow's forecast if wildfire smoke or inversion is developing.

Common planning patterns

Street canyons and traffic-heavy routes can feel worse than the regional reading.
Commuting often adds repeated outdoor platform or walking exposure.
Smoke events make overnight indoor air management much more important.

City planning checklist

  • Compare the morning and evening commute before committing to a long outdoor route.
  • Move intense workouts indoors when AQI trends upward.
  • Keep bedroom air cleaner on smoky days rather than focusing only on daytime exposure.
