The United States is currently experiencing a fire season that is intensifying faster than historical norms, while massive smoke plumes from Canadian blazes are degrading air quality across both nations. Experts point to a convergence of climate extremes as the primary driver behind a season that has already affected millions of acres across North America. As of mid-July 2026, Canada has recorded approximately 3,500 fires that have consumed 2.3 million acres. While this figure is consistent with the 10-year average for this time of year, it remains lower than the 5-year average, which was inflated by recent extreme seasons. On Thursday, more than 100 wildfires were active in Canada, with strong winds pushing smoke into the Upper Midwest and the northeastern United States, impacting millions of people. Additional smoke was contributed by large fires in Minnesota.
The situation in the United States is particularly severe. The National Interagency Fire Center reports that nearly 40,000 fires have burned over 3.6 million acres so far this year. This includes 500,000 acres consumed in just the last two weeks, a total that exceeds the 10-year mid-July average by nearly 10,000 fires and one million acres. The center has warned in a new advisory that current fire activity is mirroring conditions typically reserved for much later in the season. The American West has been the most impacted region, with Colorado and Utah facing the brunt of the damage. Of the 48 large active wildfires nationwide, 10 are located in those two states, with others scattered across California, Arizona, Idaho, Nevada, New Mexico, Oregon, and Washington. Tragically, at the end of June, the Knowles Fire along the Colorado-Utah border resulted in the deaths of three firefighters and injuries to two others.
Experts describe the current conditions as a "perfect storm." Jon Meyer, assistant state climatologist for Utah, explained that landscape, fuel, and weather conditions have converged to create one of the worst wildfire seasons in a decade. This is largely due to prolonged drought, record-breaking heat, and historically low snowpack. Researchers like Dan McEvoy of the Nevada-based Western Regional Climate Center note that the 2026 snowpack in Colorado and Utah was, in some instances, the worst seen in 50 to 75 years. This lack of snowpack, coupled with high temperatures, caused premature melting that left vegetation vulnerable to ignition an entire month earlier than usual. Similar downturns in snowpack have been observed across the northern band of Canada for decades, according to the Canadian government.
The Canadian Climate Institute has noted that fire seasons globally are starting earlier and lasting longer, often smoldering through winter as "zombie fires." While factors like forest management contribute to fire patterns, experts emphasize that the influence of climate change is significant. Stanford University scientist Noah Diffenbaugh cited research suggesting that roughly half of the long-term increase in burned acreage in the western U.S. can be attributed to climate change, meaning that without it, total acreage would be about 50% of current levels. He noted that higher temperatures increase wildfire risk by affecting both snowpack and atmospheric demand, and these trends are expected to continue despite carbon emission reduction efforts. Tim Brown, a climate researcher, added that "climate is enabling fire, and weather is driving fire," noting that the West is experiencing "hotter droughts" than in the past.
Looking ahead, the National Interagency Fire Center expects above-normal wildfire risk to persist in the West through the fall. While some models suggest a potential monsoon could offer relief to certain states, researchers warn that the region is still in the early stages of its risk calendar. McEvoy noted that the pattern is likely to shift north as summer progresses, with above-average potential expected in August and September for Northern California, Oregon, Washington, and the Northern Rockies. Furthermore, Diffenbaugh warned that the region has yet to face the Diablo and Santa Ana winds that typically drive the most dangerous autumn fires. As he put it, "There's still months to go."
Nick Nausler, of the National Weather Service's Storm Prediction Center, said the intensity is not entirely surprising "given the conditions" that preceded it.
Compounding a snow drought that raised alarms this spring as snow cover dwindled over the Rockies and Cascades, western states also faced repeated heat waves that began in March and persist into the present.
