How to read the air on this map
Wildfire smoke’s main hazard is fine particulate (PM2.5). The map shows two kinds of stations: official ECCC AQHI stations (Canada’s 1–10+ scale, labeled in their popups) and continental monitors on the U.S. AQI scale (0–500), explained below. Both rank the same pollution — the official guidance for New Brunswick is your local AQHI forecast from Environment Canada.
0–50 · Good
Air quality is satisfactory; little or no risk.
51–100 · Moderate
Unusually sensitive people should consider limiting prolonged exertion.
101–150 · Unhealthy for sensitive groups
People with heart/lung disease, kids, and older adults should limit exertion.
151–200 · Unhealthy
Everyone may begin to feel effects; sensitive groups more seriously.
201–300 · Very unhealthy
Health alert — everyone may experience serious effects.
301+ · Hazardous
Emergency conditions; stay indoors with filtered air.

How to protect yourself from wildfire smoke in New Brunswick
Stay indoors and seal up
Close windows and doors, and run your AC or HVAC on recirculate so you’re not pulling smoke inside.
Run a HEPA air purifier
A true-HEPA purifier sized to the room dramatically cuts indoor fine particulate (PM2.5) — the part of smoke that harms lungs.
Make a DIY box-fan filter
A box fan with a MERV-13 furnace filter taped to the back is a cheap, effective backup when purifiers sell out during a smoke event.
Mask up outdoors with an N95
Cloth and surgical masks don’t stop PM2.5. A well-fitted N95 or P100 does. Limit time and exertion outside when the air is smoky.
Watch sensitive groups carefully
Kids, older adults, pregnant people, and anyone with asthma, COPD, or heart disease are most vulnerable — keep medications handy and follow AQHI guidance.
Wildfire smoke in New Brunswick
New Brunswick's wildfire window peaks in spring, when dry Acadian-forest fuels burn before green-up. Most fires are small and human-caused, but dry years bring genuine forest-fire stretches across the province's timberlands. During periods of active fire, smoke can push air quality into ranges where everyone feels it — sometimes for days if weather patterns stagnate — and even areas far from the flames see hazy skies, reduced visibility, and elevated PM2.5. During fire season, checking the air daily and watching for special air quality statements from Environment Canada is a good habit for New Brunswick residents.
The map above layers Environment Canada’s smoke forecast over the latest air-quality monitor readings, so you can see both where smoke is expected and what the air actually measures at the surface. Zoom in to your community to check the nearest station readings.
New Brunswick wildfire smoke FAQ
Why is there wildfire smoke in New Brunswick right now?
Wildfire smoke travels with prevailing winds at high altitude, often hundreds or thousands of kilometres from the fire that produced it. New Brunswick can experience smoke from fires burning within the province, in neighbouring provinces, or across the U.S. border. The smoke layer on the map shows where the air is expected to be affected right now, while the fire layer shows the source fires.
How do I check the official air quality in New Brunswick?
Canada's official scale is the Air Quality Health Index (AQHI, 1–10+) from Environment and Climate Change Canada. The map shows both kinds of readings: official ECCC AQHI stations (labeled on Canada's 1–10+ scale in their popups) and continental monitors on the U.S. AQI scale (0–500) — each labeled with its own scale, and both ranking the same pollution. For official guidance, check the AQHI forecast for your community.
How do I protect myself from wildfire smoke in New Brunswick?
Stay indoors with windows closed and your ventilation on recirculate. Run a true-HEPA air purifier or build a DIY box-fan filter with a MERV-13 furnace filter. If you must go outside, wear a well-fitted N95 or P100 respirator and limit strenuous activity. People with asthma, COPD, or heart conditions, as well as children and older adults, should take extra precautions.
How often is the New Brunswick smoke map updated?
The smoke layer comes from Environment Canada's RAQDPS model, which runs twice a day with hourly forecast steps — the map always shows the current hour of the newest run. Air-quality monitor readings auto-update through the day (typically hourly per station), and the fire layer re-pulls from official Canadian feeds every few minutes.
Is this map a substitute for official warnings?
No. For official air-quality statements and special air quality advisories, follow Environment and Climate Change Canada and your provincial or local health authority. For evacuations and emergencies, follow local authorities and call 911.
