The County Fire was first reported at 2:12 pm on June 30, 2018 in vegetation alongside County Road 63 and Highway 16 in Rumsey Canyon in Guinda in Yolo County and a small part of Napa County in California. The fire was fueled by dry vegetation and was driven by red flag conditions, including high temperatures, gusty winds and low humidity. By the end of the day, the fire had burned 8,000 acres (32 km$^2$) and caused mandatory evacuations in the area.

### July

By the morning of July 1, the County Fire was burning out of control and had grown to 16,500 acres (67 km$^2$), crossing the Yolo County and Napa County line, burning west of Woodland in a rural area near Lake Berryessa. Evacuation advisories were put in place for areas south of County Road 81 and west of County Road 85, as well as areas of Solano County, and additional mandatory evacuations were put in place. By the afternoon, the County Fire was 22,000 acres (89 km$^2$), at 0% containment. The evacuation center at the grange in Guinda was closed and a new evacuation center was open in Esparto.

Containment stayed at five percent, though firefighters continued setting up containment lines. On the Fourth of July, the fire had grown to threaten 1,500 structures and was 27 percent contained. Firefighters focused on building containment lines, with inaccessible terrain causing accessibility challenges for fire crews.
