California’s wildfire season is off to its worst start in 10 years. Through Monday morning, 196,092 acres have burned across the state since Jan. 1 — an area more than nine times the size of Chico and more than double the average by July 9 of the previous five years — according to an analysis of federal and state fire statistics by the Bay Area News Group. From the Oregon border to Napa County, Santa Barbara to San Diego, thousands of firefighters with helicopters, bulldozers and air tankers are battling hot temperatures and windy conditions at a time when, most years, summer fire season has barely begun.
