Air Quality & Wildfire News — August 3, 2026

A mixed day: containment progress on the California coast, a tragic loss overseas, and continued political friction over cross-border smoke.

Woodside Fire holds within its lines on the Sonoma Coast

Crews conducted aggressive mop-up of the Woodside Fire near Timber Cove on the Sonoma Coast Sunday, working to hold the blaze within control lines ahead of gusty onshore winds, as the Mercury News reports. The fire was 50% contained and mapped at 152 acres Sunday morning, with about 135 personnel on scene. Cal Fire said four structures, including two homes, were destroyed, and fire behavior was minimal Sunday, producing less smoke than earlier in the week.

The Bay Area Air District had issued a Spare the Air Alert from Thursday, July 30 through Saturday, but lifted it Saturday morning as air quality improved significantly. Highway 1 reopened Saturday evening, though officials asked travelers to use caution near the fire.

Two firefighting crew members killed battling major wildfire west of Athens

Five water-dropping planes and five helicopters took off at first light Monday to help hundreds of firefighters battling a major wildfire west of Athens, a day after two firefighting helicopters collided midair, killing one Greek and one Danish crew member, as NBC News reports. The crew of the second helicopter, a Greek and a British national, were hospitalized with light injuries.

The fire, which started Friday near the seaside area of Psatha, has forced fresh evacuations, with more than 1,000 people evacuated so far, including over 250 rescued by boat. Greece's firefighting department said the blaze appears to have started from sparks from a faulty power line. Strong winds were dying down Monday, raising hopes crews could halt its advance, though officials warned the wider Athens region remains at high wildfire risk as temperatures climb. In France, firefighters are still guarding a burn scar four times the size of Paris.

Trump says a response to Canadian wildfire smoke is coming

President Trump said Sunday he has decided on a response to smoke drifting into the U.S. from Canada's wildfires, telling a reporter on Air Force One "I have, yeah... And you'll find out about it soon," as HuffPost reports. More than 800 wildfires are currently burning across Canada. Any measure would come on top of the 50% tariff on Canadian goods Trump announced last month over separate trade disputes.

Smoke crossing the border isn't new in either direction — Canadian crews have helped fight U.S. fires in past years, and Canadian officials have noted the U.S. has sent smoke north as well during past fire seasons.
