Washington gas prices rise to $5.27 a gallon

OLYMPIA — Average gasoline prices in Washington rose 4.2 cents per gallon over the past week to $5.27 a gallon Monday, according to a GasBuddy survey of 2,666 stations statewide.

GasBuddy said Washington prices were 92.5 cents higher than a month ago and $1.18 higher than the same date a year ago.

The national average price of gasoline rose 2.4 cents over the past week to $3.95 a gallon, according to GasBuddy. The national average was up 97.9 cents from a month ago and 83.8 cents higher than a year ago.

The national average price of diesel increased 14.3 cents from a week earlier to $5.369 per gallon, which GasBuddy said was the highest level since July 27, 2022.

According to GasBuddy price reports, the cheapest station in Washington was selling gas for $4.09 a gallon Sunday, while the highest price was $6.49 a gallon, a spread of $2.40.

Among neighboring metro areas, Tacoma averaged $5.31 a gallon, up 6.8 cents from last week’s $5.24. Seattle averaged $5.50, up 7.5 cents from $5.42. Yakima averaged $5.00, up 10.9 cents from $4.89.

Washington’s average price on March 30, 2025, was $4.09 a gallon, compared with the U.S. average of $3.11, according to GasBuddy’s historical data. On the same date in 2024, Washington averaged $4.49 and the national average was $3.52. In 2023, Washington averaged $4.27 and the national average was $3.49. In 2022, Washington averaged $4.73 and the national average was $4.24. In 2021, Washington averaged $3.26 and the national average was $2.87.

“Gasoline and diesel prices continue to climb to multi-year highs as the effective closure of the Strait of Hormuz curtails the flow of millions of barrels of crude oil each day,” said Patrick De Haan, head of petroleum analysis at GasBuddy. “The situation remains highly volatile and unpredictable, but upward pressure on fuel prices is likely to persist as long as global oil supplies are constrained by the continued disruption in the Strait. We’re likely to see the national average for gasoline push beyond the $4-per-gallon mark, while diesel could approach $6 per gallon and potentially set new records if conditions fail to improve. Americans have already spent nearly $8 billion more on gasoline over the past month, a trend that poses growing risks to the broader economy, while surging diesel prices may begin to reaccelerate inflation.”

GasBuddy said its figures were compiled from more than 11 million weekly price reports covering more than 150,000 gas stations nationwide.
