Gas prices across the United States continue to decline to their lowest levels in years — except in Washington state, where prices have risen relative to the national average. According to figures shared by the policy organization Future 42, the price gap between Washington and the rest of the country increased by six cents over the past week.
Washington’s average gas price now stands at $4.18 per gallon, compared with the national average of $3.04. The $1.14 difference marks one of the largest disparities in recent months.
The group also noted uncertainty regarding potential effects from a recent gasoline pipeline leak reported in Snohomish County, though no statewide impacts have yet been confirmed.
State-level taxes remain a significant contributor to Washington’s higher fuel costs. The state currently applies a 55.4-cent gas tax along with a 51-cent carbon tax, totaling $1.06 per gallon in state-imposed charges.
Neighboring states show substantially lower prices, with Oregon averaging around $3.81 and Idaho at $3.27, according to the accompanying map released by Future 42.
The data cited in the report originates from AAA’s gas price tracker.
