The Dove Fire near a gateway town to Yosemite National Park has disrupted California’s otherwise tranquil fire season, prompting evacuations and road closures. This sudden blaze has drawn attention to the state’s vulnerability as temperatures begin to climb.
John Buckley, a former U.S. Forest service firefighter and current executive director of the Central Sierra Environmental Resource Center witnessed the fire’s rapid spread. While driving through the Central Sierra foothills on July 26, 2026, he noticed the dry conditions and predicted the imminent risk. “We drive back, and they’re burning over at the city of Sonora,” Buckley recalled. “The fuels are now quite primed for burning, and they’re only going to get drier.”
The Dove Fire: A sudden disruption
The 226-acre blaze, suspected to have been caused by a reckless 30-year-old man, has been brought under control by firefighters. However, the looming threat of high temperatures has raised concerns about future fire activity. New research underscores the connection between heat waves and increased wildfire risks.
California has experienced a below-average fire season so far, with approximately 4,030 wildfires burning over 208,000 acres. This is significantly lower than the five-year average of nearly 5,300 fires burning more than 300,000 acres by this point in the season, according to Cal Fire data.
Heat waves and wildfires: A dangerous combination
Cal Fire Battalion Chief David Acuña cautions against using the term “quiet” to describe the current fire season. “There is a superstition that when you use words like ‘quiet, slow, bored’ in the fire station, that just means that you’re about to get hit with an amazingly busy shift,” he said.
California has benefited from favorable weather conditions so far, despite a low snowpack and a scorching March. However, this is about to change as a heat wave approaches. John Abatzoglou a professor of climatology at UC Merced warns that the state is on the brink of a significant temperature spike.
The National Weather Service offices across California are issuing warnings about soaring temperatures starting later this week. The Los Angeles/Oxnard office has indicated that conditions will shift to “dangerously hot” by Friday.
The science behind the heat-wave and wildfire connection
Recent research published in the journal Science Advances and led by scientist Dmitri Kalashnikov highlights the link between heat waves and wildfire activity. The study found that nearly half of the burned area in warm-season months from 2001 to 2026 occurred during or in the wake of a heat wave, particularly in forests.
Heat waves, defined as at least three consecutive days with temperatures exceeding the 90th percentile, account for 15% or less of the warm season. However, climate change is exacerbating their frequency and intensity. Abatzoglou explains that heat waves create chronic conditions leading to drier, more flammable fuels. They also result in hotter nights, which increase nighttime fire intensity and hinder suppression efforts. Additionally, heat waves can prime conditions for lightning, a common igniter of some of California’s largest blazes.
“And then it’s off to the races in terms of fire activity,” Abatzoglou noted. However, he emphasized that not all heat waves will necessarily lead to increased fire activity. This still depends on ignitions occurring in the right place and at the right time.
Preventing human-caused ignitions
Acuña stressed the importance of preventing human-caused ignitions. He advised Californians to mow before 10 a.m. on hot days or avoid yard work during red flag warnings. Additionally, securing tow chains to prevent sparks and avoiding parking hot cars on dry grass are crucial precautions.
California has received federal funding assistance for the Dove Fire within hours of the incident. However, a prolonged dispute between Sacramento and Washington continues over slower-moving wildfire recovery funds, including hundreds of millions in aid tied to last year’s L.A. fires that Governor Gavin Newsom stated in May that FEMA was still withholding.
As for predictions for the season ahead, Acuña remains cautious. “It depends on what the weather brings us,” he said. “If it brings us hot, windy, red flag warning conditions, then that could certainly be a problem. If it brings us rain, well, that brings us a totally different concern. We are ready to respond.”
