Washington counties’ gas prices
Average gas prices in Washington have declined slightly from yesterday’s total, but increased by 19.9 cents per gallon since last week.
AAA provided an updated database listing the best and worst counties in Washington to fill up your tank.
The most expensive counties to buy a gallon of gas in Washington are:
- San Juan, $5.608

“The West Coast may see continued increases due to seasonal refinery maintenance and the shutdown of a refinery in Southern California, which will keep supply tight,” GasBuddy wrote. “However, with the transition back to winter gasoline just a week away for most areas, those increases may be short-lived, with potential relief arriving toward the end of the month.”
Last week, Washington surpassed Hawaii to claim the No. 2 state for highest gas prices, behind only California. Washington now leads the nation in expensive gas, surpassing California by $0.005.
