Gas prices in California have surged by 44 cents over the past month, with the average cost of a gallon of regular gasoline reaching $4.82 as of Friday.

Inflation Reaches Highest Level in a Year for San Diego as Costs Rise Nationwide
The recent hike in fuel prices may be linked to a combination of reduced gasoline inventories and a refinery fire in Northern California earlier this month.
On February 1, a fire erupted at the Martinez PBF refinery, causing a statewide impact on fuel prices.

“Although Southern California does not rely on gasoline from the affected refinery, some supply from our region may be shifting to Northern California to address shortages, leading to even sharper price increases in that area,” explained Doug Shupe, a spokesperson for the Automobile Club of Southern California.
In San Diego, a gallon of regular gas now costs an average of $4.77—22 cents more than a month ago. The highest recorded average price in the region was approximately $6.44 in October 2022.
