Wildfire smoke can travel a long way. And this wildfire smoke is a serious health concern. But how far can wildfire smoke travel exactly? Can someone in New York be affected by the California wildfires thousands of miles away? Do Australian forest fires affect the entire country?

How Fast Does Wildfire Smoke Travel?

In July 2023, wildfire smoke from Canada enveloped the East Coast, causing thick haze and putting 100 million people on air quality alerts. 

Rising warm air on land has lifted the smoke to elevations ranging from 5,000 to 20,000 feet, where it is being pushed south and east by strong winds. Smoke swiftly traversed a distance of 2000 kilometers from Alberta to Northeast Manitoba in under 15 hours, average speed is 130 km/h.

Climate change and human intervention in the landscape have conspired to make wildfires larger and more powerful, sending clouds of toxic smoke from Canada to the East Coast and across entire continents.

During the ravaging California wildfires in September of 2020, New York City residents were wondering this exact question. Could this smoke be from the wildfires out west? Can smoke travel that far?

As it turns out, it was! Satellite images confirmed the wildfire smoke traveled across the entire country to New York.

As we can see, wildfire smoke can travel quite far. But what determines how far it travels? Does it typically travel this far? Let’s dive further into how far wildfire smoke can travel.

How Far Can Wildfire Smoke Travel?

Smoke trapped at lower altitudes is far less likely to travel more than a few hundred miles. This smoke typically only affects the surrounding local communities near the fire. 

But larger, more powerful wildfires can launch smoke to far higher altitudes. This can result in smoke traveling thousands of miles in the earth’s stratosphere. In fact, astronauts have captured this from space!

At any moment, changes in weather patterns can move this dangerous smoke back down to the earth’s surface, affecting air quality thousands of miles away from the original wildfire.

As seen below, heavy smoke from California wildfires on the West Coast can make its way all the way to the East Coast. Bushfire smoke in Australia can also easily travel to all parts of the country.

California Wildfires Reach as Far as the Netherlands

Wildfires are truly a global problem. Smoke from California’s destructive wildfires of September 2020 was seen from satellite images all the way in Europe and the Netherlands.

Wildfire smoke contains dangerous PM2.5 pollutants that are a huge hazard to our health. It’s essential that we understand the danger PM2.5 air pollution poses to our bodies so that we may better protect ourselves from wildfire smoke and air pollution.

How High Does Wildfire Smoke Go?

As a wildfire burns, large amounts of smoke are launched into the air. The stronger the wildfire, the higher the smoke reaches in the atmosphere. The higher the smoke reaches, the farther the smoke can travel. 

In some cases, this smoke can form an explosive storm cloud called Pyrocumulonimbus. These explosive clouds can launch the smoke even higher, reaching over 5 miles above the surface of the earth into the stratosphere.
