Why WA gas prices hover near highest in US
Washington state recorded the highest average gas prices in the nation on June 22, 2023, surpassing California and Hawaii. As of September 22, 2025, the average price for a gallon of unleaded gas reached $4. 59, significantly above the national average of $3. 16. Prices were higher in Seattle and King County, at $4.
64 and $4. 61 respectively, while surrounding counties saw slightly lower prices. Factors contributing to the high prices include limited refinery capacity, increased demand due to population growth, and state policies such as the Climate Commitment Act, which has raised gas prices by an estimated 25 to 50 cents per gallon. The state legislature also increased the gas sales tax, further elevating costs. The practice of "zone pricing," where refiners set different wholesale prices based on demand, has been criticized as price gouging yet remains legal in Washington.
Consumers are urged to conserve gasoline and consider alternative transportation to alleviate rising costs. The Attorney General’s report emphasizes the need for individual action to combat high fuel prices.
