As wildfires in Los Angeles began to subside late last week, Baja California, just south of the U.S.-Mexico border, faced its own wave of devastating blazes.
Satellite images released by NASA's Earth Observatory captured the vast scope of the fires from space. By Sunday, the flames had consumed over 28,000 acres across the Baja California peninsula.
The striking image, taken by the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA's Aqua satellite, shows a thick plume of smoke stretching out over the Pacific Ocean. This smoke was driven by the strong Santa Ana Winds, which intensified the fires and spread the devastation along the coastline.

Why This Matters
The fires in Baja California closely resemble those in Los Angeles, underscoring the escalating wildfire risks across the southwestern region of North America.
The Santa Ana winds—hot, dry gusts descending from inland mountains—and severe drought conditions have created a perfect environment for wildfires to ignite rapidly and spread uncontrollably.
The impact of these wildfires extends far beyond the flames. Smoke can travel hundreds of miles, significantly degrading air quality and posing serious health risks, particularly for individuals with preexisting respiratory or other health conditions.
What to Know
As of Sunday, three active wildfires were burning in Baja California, according to Mexico's National Forestry Commission.
Some 28,000 acres have so far been burned, with firefighters attempting to quell the flames. One fire had been completely extinguished after burning 160 acres.
The image released by NASA was captured at 1:44 p.m. PT on January 23, 2025, and shows a fire raging in the El Escondido area of Ensenada, about 50 miles south of the U.S. border.
Gusts of wind upwards of 50 miles per hour were reported across the state, according to the Baja California Civil Protection Office.
Meanwhile, much of the northern half of the Baja California peninsula is under extreme drought conditions following months of little to no rain.
What People Are Saying
The National Forestry Commission said in a post on X (formerly Twitter): "If you see a forest fire, report it immediately and do not try to put it out."
Adam Voiland, senior science writer and editor for NASA Earth Observatory, wrote in a post about the new images: "Hot, dry weather and strong winds fueled wildland fires in Baja California in late January 2025. Seasonal Santa Ana winds blew in from dry areas inland and accelerated down the Sierra Juarez mountain range, creating conditions where a few sparks and small brush fires could quickly escalate."
What Happens Next
Some showers will bring rain to the affected area throughout Monday; however, much of the rest of the week looks set to be dry and warm in Baja California, which could hamper firefighting efforts.
The strong Santa Ana winds have, at least, died down for now, which should help slow the spread of further fires.
It's unclear how many people and properties have been affected by the fires at this time. Newsweek contacted the National Forestry Commission via email for further comment.
