“You are literally the only state that is above where it was one year ago,” Patrick De Haan, the head of petroleum analysis for GasBuddy, said regarding Washington’s fuel prices.
As of June 20, Washington held the third-highest price per gallon of gas in the country, behind only California and Hawaii.
Closures and disruptions in California’s gasoline refineries may be to blame, as modern West Coast refineries have a ripple effect on local markets, which include Washington, The Center Square stated.
“Washington’s really been impacted by some events that have been kind of out of your state,” De Haan told The Center Square. “Refinery issues are probably why you’re higher than a year ago.”
Two major refineries in California are scheduled for closure: the Phillips 66 refinery in Los Angeles, which is set to close by October, and Valero, which will close its refinery by April 2026. Additionally, a fire at the Martinez Refining Company in California in February led to a noticeable 21-cent increase in Washington gas prices.
Another variable involved in rising gas prices is the heightened tensions in the Middle East, as Israel and Iran engage in aerial attacks.
Washington’s new gas tax, scheduled for July 1, would also increase the price per gallon by six cents, with a three-cent increase for diesel fuel per gallon.
