Where are the fires in Canada right now?

This map plots the latest NASA FIRMS satellite fire detections in the Canadian portion of the North America feed. The map and timestamp update when the live feed refreshes.

Is wildfire smoke coming to the United States?

A fire detection does not by itself say where smoke will travel. Wind, plume height, and weather determine whether smoke reaches a city, so check the live air reading and local forecast for your location.

How current is this wildfire map?

The NASA FIRMS detections are collected hourly and the stored summary is served from cache. Each map view shows the timestamp of the last completed collection.

Fire detections across the continent

Each ochre point is a real FIRMS detection. Clusters show where the current feed is most active; they do not predict smoke direction.

Fire proximity is not an air-quality reading. Open a city to see the measured air and the cleaner places within a drive.

What the map can’t tell you

Three useful limits

Where are the fires in Canada?

The Canadian detections are plotted here from the same North America FIRMS feed. Use the timestamp, then open the nearest city’s live reading: fire location and breathing-level smoke are related, but not interchangeable.

Is the smoke coming to the US?

Sometimes, but the map alone cannot answer that. Wind and plume height decide where smoke travels. Check your live air and the forecast before changing outdoor plans.

How current is the map?

The collector runs hourly and the page displays the last completed collection. Satellite detections are a signal that fire is present, not a promise about what your monitor will read.
